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

Merardo Magana Garza was lovingly known as “Tano.” He was adored by many in the city of Mission and was known to be a sharp dresser and a ladies' man. The 63-year-old father was found dead on April 18, 2006 west of Los Ebanos. According to Chavez, at the time investigators could not determine Garza’s cause of death. “Officials were unable to see or say how he died because his body was burned and decomposed,” said Chavez. “But, it was ruled as a homicide, the cause is just undetermined.” Garza still had his jewelry when officials found him, according to Chavez... Chavez said investigators have been unable to reach out to family members for new leads and investigators have no trace of the immediate family. ValleyCentral located his obituary, which said Garza was married with children.

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.
