CAMERON COUNTY, Texas (ValleyCentral) — Murder remains unsolved after 18 years since a body of an almost unidentifiable body was discovered in a canal. Gregory Allen Meredith, 43, body was discovered floating in a canal by a fisherman on May 7, 2003. Cameron County Sheriffs deputies responded to the scene located along Old Port Isabel Road and Highway 100 at 6:45 p.m. Deputies responded after receiving a call from the Laguna Vista Police Department. Officials could not immediately identify Meredith’s body due to severe water damage as well as the fact that his teeth had all been removed, making it impossible to check dental records. Meredith’s body was believed to have been in the canal for two to three days. Meredith’s body was initially reported to have two gunshot wounds, one behind his ear and another at the base of his skull. A preliminary autopsy later revealed that Meredith had eight bullets lodged in his skull. Cameron County Sheriffs Spokeswoman at the time, Elizabeth Anguiano told Valley Morning Star reporters that Meredith was identified as the Federal Bureau of Investigation was able to “get two prints from him.” Fingerprints matched the criminal file of Gregory Allen Meredith out of Bastrop, located southeast of Austin. Authorities told reporters they did not believe the murder was the result of a robbery as Meredith had $115 dollars in his pocket. According to CCSO Meredith was believed to have been involved with a small organization that trafficked meth from Austin. CCSO does have a suspect, however, no arrests have been made. This investigation is ongoing. If you have any information on this case, please call the Cameron County Crime Stoppers at their hotline: (866)-350-5551 or (956)-350-5551.

HARLINGEN, Texas (ValleyCentral) – A woman well known by the community disappeared with no trace only for her flesh-eaten body to be discovered days later in a resaca, leaving authorities with no leads. 23 years later, the murder of Maria Marisella Gonzalez remains unsolved. Also known as “Marcie,” Gonzalez was a dancer at Crazy Horse Topless Bar. Gonzalez was last seen spending time in Harlingen’s La Placita district on June 8, 1998. Witnesses told authorities that Gonzalez was seen entering a vehicle with a man. The dancer was discovered dead in a resaca near Hudson Road outside San Benito on June 14, 1998, according to the Cameron County Sheriffs’ Office. Gonzalez’s body was found with multiple skull and facial fractures with her face flesh eaten away by “whatever lies in the murky waters.” The 35-year-old woman was identified as “Marcie” through her clothing, jewelry, and the tattoo of a rose on her right shoulder. According to an autopsy report released at the time, Gonzalez’s cause of death was determined to be three blows to the head and face delivered with a blunt object. Preliminary pathology reports ruled her death as a homicide. CCSO Investigator at the time Domingo Diaz told reporters that the agency has questioned all of Gonzalez’s acquaintances but had no leads. Diaz stated that he was sure that “someone saw… something.” As a rise in murders spiked during the time of Gonzalez’s death, reporters spoke with other county officials. Hidalgo County District Attorney Rene Guerra emphasized the importance of witnesses, stating murders like Gonzalez’s, that lack witnesses tend to go unsolved. 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.

Cold Case Spotlight

A 47-year-old man has been charged with capital murder after authorities say he confessed to shooting and killing two women in rural Edinburg on Tuesday evening. Alvaro Medrano, 47, of Edcouch was charged with capital murder, a capitol felony, on Wednesday. A Hidalgo County Justice of the Peace set bond at $2 million. At about 6:48 p.m. on Tuesday, Sheriff’s deputies responded to an area near Sunflower Road in rural Edinburg in “reference to a 911 caller reporting that he had shot his wife“, according to a news release from the Hidalgo County Sheriff’s Department. Deputies located Medrano as he was walking away from the location, and detained him without incident near Farm-to-Market Road 493 and Farm-to-Market Road 2812, according to the news release. When deputies responded to the Medrano’s residence, they found two female bodies inside of a vehicle with gunshot wounds to the head. The bodies were identified as Medrano’s wife, 30-year-old Olga Espinosa, and Medrano’s mother-in-law, 52-year-old Irene Espinosa, according to the news release. Hidalgo County Sheriff’s Office investigators and Crime Scene Specialists collected evidence from the scene, including the handgun that was used in the shootings, according to the news release. After an investigation, the Hidalgo County Sheriff’s Office “learned that Medrano had streamed his confession on Facebook Live, while walking away from the crime scene,” according to the news release. Investigators are working with the Facebook Law Enforcement Compliance Department to preserve the livestream as evidence. During an interview, Medrano confessed to killing his wife and mother-in-law in a domestic disturbance due to infidelity, according to the news release. The Hidalgo County Sheriff’s Office encourages anyone who may be a victim of domestic violence to seek help from their respective law enforcement agencies.
