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

BROWNSVILLE, Texas (KVEO) — This month marked 31 years since the murder of Alan E. Bossom was discovered. After a long day, many people can relate to feeling sluggish while driving home, so when a passerby reported a man asleep at the wheel they did not think that the man could be found dead. On July 4, 1990, Alan E. Bossom was found dead at the wheel of a vehicle at the intersection of Robindale Road and FM 3248 in Brownsville. Bossom had been in town for a couple of days before being discovered murdered. Chief Deputy at the time, Carlos Tapia, reported what sheriff’s deputies had seen when having responded to the crime scene. Tapia stated “they found Bossom inside a 1977 Chevrolet station wagon, slumped over the steering wheel,” according to an article from the Valley Morning Star. Deputies believed the man was asleep, however, after further observation, it became clear that Bossom had been murdered. Bossom had suffered a gunshot wound to his head. He was officially pronounced dead at the scene by the Justice of the Peace at the time, Tony Torres. Investigation revealed that family members did not know he was in town. This investigation remains active and no arrests have been made.

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.
