Rio Grande Valley Friends and Families of Murdered Children

Proudly Introduces the RIO PROJECT COLD CASE HOMICIDE DATABASE: A Regional Initiative to Spotlight Unsolved Murders and Amplify the Voices of Victims and Their Families

The Rio Grande Valley Families and Friends of Murdered Children (RGV-FFOMC) is honored to announce the launch of the Rio Project Cold Case Homicide Database—a first-of-its-kind initiative designed to centralize and bring public attention to unsolved homicide cases throughout the Rio Grande Valley. This comprehensive and publicly accessible database will be a powerful tool for elevating awareness, supporting grieving families, and encouraging renewed investigative efforts.

Phase I – County Coverage:
The initial rollout will include unsolved homicide cases submitted from the following four counties:
  • Hidalgo County
  • Cameron County
  • Starr County
  • Willacy County

Each entry will be verified and submitted by either:
  • Local law enforcement agencies, or
  • Surviving family members seeking to keep their loved one’s memory alive and case visible.
RGV-FFOMC plans to expand the database to include additional counties across the region as resources allow.

Why This Matters:
Keeping a homicide victim’s case in the public eye not only honors their memory but also increases the likelihood of generating new leads, witnesses, or information that may help bring justice—visibility matters. Awareness saves cases.

How to Submit a Case:
Families or law enforcement agencies wishing to submit an unsolved homicide case for inclusion may do so by completing the official Case Summary -
Cold Case Submission - Google Forms

Submission Form. Submission does not guarantee immediate inclusion; all entries are subject to verification and review.

⚠️ Please Note:

Rio Project Cold Case is not a private investigative service. This initiative is strictly for public awareness and advocacy purposes. All investigative matters remain under the jurisdiction of the appropriate law enforcement agencies.

Cold Case Spotlight

HARLINGEN, Texas (ValleyCentral) — Always chosen for jury duty, a man went missing days before trial. His family searched across borders when his body was discovered shot multiple times in a canal. Three decades later, the murder of Joseph Michael Escobedo remains unsolved. Escobedo was a student at Texas Southmost College and a member of the Knights of Columbus, with ambitions to possibly become a teacher, according to reports at the time. The 23-year-old man said goodbye to his family for the last time as he headed out the door for a night out on January 2, 1992. The next day, Escobedo’s parents noticed their son’s absence as his bedroom seemed untouched. Growing concerned following a call from Escobedo’s boss stating he had not arrived for his shift, his father began a search. Escobedo’s father searched jails and police stations in Harlingen, Brownsville, South Padre Island, Reynosa, and even Matamoros. However, there was no trace. After waiting 24-hours, the Escobedos filed an official missing person report with the Brownsville Police Department. On January 4, 1992, Escobedo’s “bullet-riddled” body was discovered that same afternoon in a canal along Schmoker Road, outside Harlingen city limits near Valley International Airport, according to the Cameron County Sheriff’s Office. Authorities said Escobedo was shot eight times with two different weapons. Investigators spoke with Escobedo’s friends who claimed that they last saw him leaning against a car in the parking lot at the Genesis nightclub in Brownsville. Police were not able to determine whether he left by himself or whether someone picked him up. Feeling like they took a “part of [her] heart out,” Escobedo’s mother explained to investigators that her son was a good citizen. Emphasizing how much he enjoyed jury duty, as it was one of his “favorite hobbies.” The mother told reporters with the Valley Morning Star at the time that Escobedo was actually expected in court within days of his disappearance and murder. Escobedo was set to attend the trial of a county case on January 6, 1992. Lieutenant Ernesto Flores with the Cameron County Sheriff’s Office told reporters at the time that they could not find a motive. Adding that Escobedo “had a lot of friends, but few enemies.” In their son’s memory, the Escobedos planted a white rose bush under Michael’s bedroom window shortly after his death. Escobedo’s mother shared that she takes the roses that have blossomed to his grave. This case remains an open investigation. Individuals with any information on this case are asked to call the Cameron County Crime Stoppers at their hotline: (866)-350-5551 or (956)-350-5551.

August marks 15 years since Ruben “Yiyo” Tarin de Patino was found murdered. Yiyo, 21, was found dead East of Wisconsin Road in the city of Edinburg in 2005. “He was found burned,” said Hermelinda Chavez with the Hidalgo County Major Crimes Unit. Yiyo was described by family and friends as confident and proud. “She was described as a person who didn’t like to hide her lifestyle,” said Chavez. “She was never ashamed of how she dressed and she was very outgoing with a lot of friends.” Yiyo was last seen by her mother on July 27. She had met several friends and her sister during the day and assisted another friend with car trouble. Yiyo came home and told her mother she was meeting yet another friend, this was around midnight. “She would visit a lot of nightclubs around the area, McAllen and Edinburg,” said Chavez. “She was not aggressive but definitely defended herself.” Chavez added all of the friends that Yiyo met on July 27 were interviewed and had alibis. Investigators and family never confirmed who she had met, according to Chavez. “Family never knew who she met, it was never confirmed,” said Chavez.

Cold Case Spotlight

Hidalgo County Sheriff Eddie Guerra announced Thursday that a 40-year-old Edcouch man recently confessed to killing a woman and dumping her body in a septic tank. Aristeo Garcia Cervantes, 40, of Edcouch confessed to killing a woman and hiding her body in a septic tank, Guerra said Thursday morning during a news conference at the Sheriff’s Office. Cervantes said he killed the woman roughly 10 to 12 years ago and didn’t remember her name, Guerra said, adding that investigators believe the murder occurred in 2004... The Sheriff’s Office started investigating the murder on July 26, 2017, when someone called to report human remains in a septic tank, Guerra said. Investigators went to a home near Edcouch, where Cervantes’ daughter and her boyfriend said they’d been having problems with the septic tank. When the boyfriend and another man attempted to fix the problem, they found a woman’s boot in the septic tank, Guerra said. After they removed the boot, they found a large bone — and called the Sheriff’s Office. Investigators sent the body to a private forensic lab in Virginia for DNA testing, Guerra said. The Sheriff’s Office researched missing women and welfare concerns during the time period, attempting to identify the woman. Investigators are currently talking with a family.
