The rapes and murders of Jennifer Lee Ertman and Elizabeth Christine Peña, two teenage girls from Houston, Texas, aged 14 and 16, respectively, occurred on June 24, 1993. The murder of the two girls made headlines in Texas newspapers due to the nature of the crime and the new law resulting from the murder that allows families of the victims to view the execution of the murderers. The case was also notable in that the state of Texas rejected attempts by the International Court of Justice to halt several perpetrators' executions.

Elizabeth Christine Peña (June 21, 1977 – June 24, 1993) and Jennifer Lee Ertman (August 15, 1978 – June 24, 1993) were close friends who both attended Waltrip High School.^[1]

Although the girls were just over one year in age difference, both sets of parents approved of their friendship, with Peña's father viewing Ertman—a modest girl who had only recently begun experimenting with makeup—as a "positive influence" on his daughter, later recollecting that, shortly after the two became friends at Waltrip High School, Peña "just straightened up her act" following a brief streak of teenage rebellion in his daughter before her 1992 enrollment at the school.^[2]

At 4:15 p.m. on June 24, 1993, Ertman's father, Randy, drove his only daughter to Peña's home. At approximately 8 p.m., Peña's mother, Melissa, drove the two girls to the home of their friend Gina Escamilla, who lived in the Spring Hill Apartments and who was hosting a pool party for her school friends. As both girls exited the car, Peña assured her mother she and her friend would be home by their agreed 11:30 p.m. curfew.^[3]

When the pair realized they were going to be late returning home, they decided to leave the party to conform to the curfew both had promised their parents.^[4]

Ertman and Peña decided to take a 10-minute shortcut to Peña's residence in Oak Forest by following the railroad tracks and passing through T.C. Jester Park.^[5] This location was approximately one mile from Peña's home.^[6]

The girls were walking along White Oak Bayou when they encountered six "Black and White" gang members drinking beer shortly after holding the gang initiation ceremony of 17-year-old Raul Villarreal.^[7]

Villarreal had not been a member of the Black and White gang or any gang but had engaged in this initiation ceremony whereby he had been forced to fight several gang members for five minutes successively before they judged whether to accept him. By approximately 10:30 p.m., Villarreal had successfully fought two gang members before being beaten midway through his fight with the third member. As he lay writhing and moaning on the ground after being temporarily knocked unconscious, the gang members conferred privately to discuss whether to accept Villarreal as a member.^[8]

Minutes later, the leader of the gang, Peter Cantu, approached Villarreal, exclaiming: "You're in! Dude, you're a badass! You're welcome to hang with us anytime!" Villarreal then sat alongside the other gang members, relaxing, talking, trading insults and compliments, and drinking beer. Shortly thereafter, he held a beer aloft, proclaiming things were to be great.^[9]

Within approximately 40 minutes of Villarreal accepting several bottles of beer from the other gang members and holding his first beer aloft,^[9] Ertman and Peña passed the gang. One member, José Medellín, attempted to grope and pinch one of Peña's breasts; Peña brushed aside Medellín's hand and continued walking. In response, Medellín stated: "No, baby! Where [are] you going?" He then clasped his arm around Peña's neck, threw her to the ground, and dragged her down a gravel decline in the direction of the other gang members as Peña screamed and pleaded for help. She was then forced to remove her underwear.^{[10][n 1]}

Ertman could have easily run to escape at this point, but ran to help her friend. She was thrown to the ground by gang members Peter Cantu and Derrick Sean O'Brien.^[12]

Five of the gang members proceeded to rape both girls for more than an hour repeatedly. Both girls were raped and beaten by all of the gang members with the exception of Medellín's 14-year-old brother, Venancio, on a minimum of four occasions.^{[n 2]} According to trial testimony, both Peña and Ertman repeatedly glanced in the direction of one another several times throughout their ordeal in likely gestures of concern and despair.^[14] Both repeatedly struggled against their abusers, with Peña on at least one occasion attempting to fight off her attackers by repeatedly kicking her legs, and Ertman biting her attackers. According to later testimony, on one occasion, Peña glanced in the direction of her younger friend as she was raped by Efrain Pérez and began weeping as she observed Ertman.^[15]

Realizing that the girls would be capable of identifying them, Cantu^[16] ordered the members to kill the girls. He told Venancio Medellín to stay behind because he was "too little to watch." The other gang members forced the girls into a wooded area. Both girls were strangled to death.^[5] Following Cantu's initial instruction, Villarreal first shouted, "Get on your knees, bitch!" to Ertman. O'Brien and Villarreal strangled Ertman with O'Brien's red nylon belt before breaking the belt. Both completed the act by strangling the girl with a shoelace in Peña's presence.^[7][1]

As Ertman was murdered, Peña was forced to watch her friend's death as other gang members held a ligature around her neck. At first, Peña desperately attempted to appease her abusers as she wept, offering her phone number so they could "get together". She then attempted to flee. In response, Cantu tackled and repeatedly kicked the girl in her face and body, dislodging three teeth and fracturing several ribs.^[17]

Cantu, José Medellín, and Pérez then strangled Peña to death with shoelaces. The gang members stomped on both girls' throats to ensure their deaths.^[5]

Leaving the crime scene, Cantu handed Venancio Medellín a Goofy wristwatch taken from Ertman's body, saying, "Take this, I don't want it."^[18]

Cantu dropped off José Medellín, Pérez, and Villarreal at his residence, where he lived with his brother, Joe Cantu, and sister-in-law, Christina Cantu. Christina Cantu questioned why Villarreal was bleeding, and Pérez had a bloody shirt. This prompted Medellín to say the gang "had fun" and that details would appear on the news. He, Pérez, and Villarreal then elaborated that they had raped both girls.^[19]

Peter Cantu then returned and divided the valuables that had been stolen from the girls. José Medellín got a ring with an "E," so he could give it to his girlfriend, Esther. Medellín reported that he had killed a girl and noted that he would have found it easier with a gun. After the gang left, Christina Cantu convinced Joe Cantu to report the crime to the police.^[20]

Four days after the murders, the girls' bodies were found in the park during hot weather conditions.^[21] Both bodies had significantly decomposed, and dental records were used for identification. O'Brien was videotaped smiling at the scene of the crime. The medical examiner corroborated that the cause of death was strangulation. All those believed responsible were ultimately arrested. Medellín gave both written and taped confessions.^[22][23][24]

At sentencing, the offenders were remanded to the Texas Department of Criminal Justice (TDCJ) system. Peter Anthony Cantu, José Ernesto Medellín, Derrick Sean O'Brien, Efrain Pérez, and Raul Omar Villarreal received death sentences. Venancio Medellín, the brother of José Medellín, testified against four of the gang members (everyone except his brother). He received a 40-year prison sentence, the maximum for a juvenile, for the sexual assault of Jennifer Ertman.

Following Roper v. Simmons, when the Supreme Court of the United States banned the executions of people who committed crimes while they were below 18 years of age, the death sentences of Pérez and Villarreal were automatically commuted to life in prison.^[7] Pérez will become eligible for parole on October 10, 2029, while Villarreal will become eligible for parole on September 20, 2029.^[25][26]

Cantu, O'Brien, and José Medellín were later implicated in the January 4, 1993, murder of 27-year-old Patricia Lopez.^[27] Although none of them were charged (Cantu had already been sentenced to death by the time he was linked to Lopez's murder), Lopez's murder was mentioned in the sentencing phases of O'Brien and Medellín. O'Brien gave a taped confession where he admitted to being at Lopez's murder but was "too drunk to know who did what."^[28] A beer can with O'Brien's fingerprint on it was found beneath Lopez's body, while Medellín's DNA was also found to be a match for DNA found at the crime scene.^[29]

Derrick O'Brien was the first to be executed on July 11, 2006.^[5][30]

Before his execution, O'Brien expressed his regrets for his actions to the families of Peña and Ertman. He then apologized to his family before being executed by lethal injection. In response to accusations from anti-death penalty advocates that capital punishment is a cruel and unusual form of punishment, Peña's father later remarked O'Brien's death had occurred peacefully, "in twenty seconds", adding: "I wish to God that my daughter could have died that easily. Put a needle in her arm and just go to sleep. I wish to hell he could have died the way she died."^[31]

José Medellín appealed his execution, saying that he had informed City of Houston and Harris County police officers that he was a Mexican citizen and that he had been unable to confer with Mexican consular officials. The prosecutors said that Medellín never told authorities he was a Mexican citizen. Medellín said in a sworn statement that he learned that the Mexican consulate could assist him in 1997.^[32] He petitioned the Texas Court of Criminal Appeals in 1998 regarding this issue; the appeal failed.^[33]

Medellín's impending execution became an international controversy since the state did not hold a hearing about whether the inability of Medellín to meet with Mexican consular officials harmed his defense. The right of a defendant to talk with his or her consulate is specified in the Vienna Convention on Consular Relations; the United States is a party to the convention, although the U.S. withdrew from compulsory jurisdiction in 1986 to accept the court's jurisdiction only on a case-by-case basis.^[34] In 2004, the International Court of Justice responded to a lawsuit filed by Mexico against the United States; the court ordered hearings to be held for inmates, including Medellín, who were denied consular rights.^[35]

In 2005, President George W. Bush ordered hearings to be held. The State of Texas, represented by Solicitor General Ted Cruz, challenged Bush's order, and the Supreme Court of the United States ruled that only the Congress of the United States has the right to order hearings to be held. In July, the ICJ ordered a stay of Medellín's execution. Governor Rick Perry argued that Texas is not bound to ICJ rulings. Death penalty opponents protested the impending execution. The families of both Ertman and Peña strongly favored the execution(s).^[5]

José Medellín was executed at 9:57 p.m. on August 5, 2008, after his last-minute appeals were rejected by the Supreme Court.^[36] Governor Perry rejected calls from Mexico and Washington, DC, to delay the execution, citing the torture, rape, and strangulation of two teenaged girls in Houston 15 years before as just cause for the death penalty.^[37] During his lifetime, Randy Ertman advocated strongly against granting parole to Venancio Medellín.^[38]

Seventeen years after the crimes, Peter Anthony Cantu was executed on August 17, 2010.^[39] The lethal injection was performed at 6:09 p.m., and at 6:17 p.m., Cantu was officially pronounced dead. He declined to make a final statement before his execution.^[40]

Cantu, Medellín, and O'Brien are buried at Captain Joe Byrd Cemetery.^[30][41][42]

The parents of Peña and Ertman successfully advocated for the State of Texas to allow victims' relatives to have permission to witness executions in Texas.^[7] Before the murders, Houston officials had stated that gangs were not a significant issue in the city. C.E. Anderson, a Houston Police Department officer who worked on the murder case, described the murder as "part of the impetus for the antigang programs in Houston." Jennifer Latson of the Houston Chronicle said that the deaths of the girls "shook" the Oak Forest neighborhood of Houston "to its foundation."^[43]

Randy Ertman, the father of Jennifer Ertman and victims right advocate, died of lung cancer on August 18, 2014.^[44] Ertman had wanted to have Andy Kahan, the City of Houston's crime advocate, to witness the executions of O'Brien and Medellín. TDCJ refused to permit Kahan to witness the execution.^[45]

The Texas parole board denied parole on several occasions to Venancio Medellin, most recently in 2020.^[46] Medellin is scheduled to be released in 2034.

Waltrip High School has a memorial to the girls.^[47] Another memorial exists at T.C. Jester Park.^[43]

They are both buried at Woodlawn Garden of Memories Cemetery.
