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

EDINBURG, Texas (ValleyCentral) — Michael Jason Buckelew and Enedelia Benavides, a deaf couple who met in college, were murdered during a trip to Edinburg. Two days after the 20-year anniversary of the murder, the case remains unsolved. ValleyCentral spoke with officers with the Edinburg Police Department, the lead agency in the investigation, to get more According to police, both Buckelew and Benavides were deaf. They met in college and had a group of friends that were also deaf. In August 2002, the two, who were living in Houston at the time, made an “abrupt” trip to Edinburg to visit family. On the night of Aug. 25, 2002, the two decided to attend a quinceañera with friends part of a deaf community.information on the case. Buckelew and Benavides left the quinceañera, and arrived back at a trailer home located at 6300 block of Gold Avenue in Edinburg. Within minutes of arriving back at the residence, a man covering his face with a bandanna made a forcible entry into the residence. The man shot Buckelew, Benavides and a third female victim. “This is more than likely a targeted incident,” Oscar Trevino, Edinburg PD Lt., said. “Somebody had to have followed them home.” A fourth victim at the residence, another female, was hidden behind a door unbeknownst to the shooter, police believe. She was not harmed in the shooting. According to police, both Buckelew and Benavides died as a result of the shooting. One died at the scene, and the other died at a hospital. The third victim in the shooting sustained “very serious injuries” and was airlifted to a military hospital for treatment. A witness that lived in the area told investigators they heard shots nearby. They then looked out the window and caught a glimpse of the suspect. The description of the suspect remains vague. He is described as an average-sized male, who had his face covered during the attack. He was said to be wearing dark clothing and driving a black passenger vehicle that appeared to be new, with shiny rims. The witness saw the suspect as he left the residence, and ran to the awaiting car. It is unknown whether there were others in the vehicle. When asked about the scene of the crime, authorities stated it seemed like a fast attack. It is not known whether anything was taken from the residence, but the surviving witness said everything happened quickly. The investigation of this case was particularly complex because the network of friends and associates that the victims had were also deaf, police said. Special arrangements needed to be made, including having interpreters available during the course of the interviewing process. Detectives with the Edinburg Police Department received assistance from the Texas Rangers. The agencies went to different parts of Texas where they conducted more interviews and executed search warrants with the attempt to find new evidence. “We exhausted everything,” Treviño said. Police said they continue to keep in contact with the family and remain ready for any kind of lead. “As law enforcement, as humans, we want to give them closure,” Gabriel Vela, Edinburg PD Lt., said. “Some time has passed but were more than willing to receive any type of information — and we will follow up on it as if it was the day after the incident.” Those with information on this case are asked to contact the Edinburg Police Department at (956) 289-7700, or the Edinburg Crime Stoppers at (956) 383-TIPS (8477).

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.
