HARLINGEN — Three people have been arrested in connection with the murder of a man who was found dead in an irrigation canal in west Harlingen.

The victim, an adult male, appears to have been shot at least once. Police have a possible identity, but they haven’t confirmed it.

Gregorio Ramirez, 33, of Primera and Mayra Camera, 22, of Brownsville were both charged with murder, arson, tampering with evidence and engaging in organized criminal activity. His bond was set at $800,000. Her bond is set at $500,000

Jesus Antonio Ramirez 30, of Primera was charged with a failing to report a felony, tampering with evidence and engaging in organized criminal activity, with bond set at $195,000.

The case started about 4 a.m. Friday morning when witnesses heard people arguing inside a late model Ford pickup truck in the parking lot of the Best Western Hotel at 4317 S. Expressway 77 in Harlingen.

As the truck was leaving the lot, the witnesses told police they heard a gunshot and saw a muzzle flash.

Four hours later, a pickup matching the description of the truck was found burning on a canal bank in a farm field off of Wilson Road, just west of Bass Boulevard. It was a late model Ford F150 four-door truck.

An intensive investigation ensued involving Harlingen police, sheriff’s deputies and state and federal law enforcement officers, Police Chief Jeffry Adickes said.

That led to the arrest of the three people Saturday night and the recovery of the victim’s body Sunday.
