Harlingen police have arrested their fourth suspect in a double murder that took over the weekend on a downtown street.
Invesetigators told Action 4 News that 18-year-old Lee Sanchez is facing tampering with evidence and engaging in organized criminal activity charges in connection with the case on Wednesday.
Both 23-year-old Edgar Villanueva and 23-year-old Agustin Gonzalez, Jr. were killed off West Harrison Avenue and B Street late Saturday night.
Police arrested three suspects: Jose Luis Vega, his brother Baldemar Vega and their cousin Jerardo Olivarez for their roles in the case.
All three suspects and the victims had different criminal pasts.
Investigators had been searching for the assault rifle used in the fatal double shooting in a local canal.
Police said Sanchez gave authorities information that allowed investigators to recover what they believe to be the murder weapon at a home off Hodes Road in the Las Palmas-Juarez area of Harlingen.
Sanchez appeared before Harlingen Municipal Court Judge Robert Guerra on Thursday morning where he was issued $120,000 dollars in bonds.
Public records show that Sanchez lives at the Williams Road Trailer Park at 301 Williams Road in San Benito.
Cameron County Sheriff's Department deputies arrested Sanchez back in May when he tried to stab a man named Gilberto Macias at a home at 4310 Hodes Road in the Las Palmas-Juarez area of Harlingen.
Deputies charged Sanchez with aggravated assault and resisting arrest.
The 17-year-old was released from the Cameron County Jail after posting $36,500 dollars in bonds while the cases from the Las Palmas-Juarez incident remain pending in court.
