The Hidalgo County Sheriff’s Office on Wednesday arrested a suspect in the shooting death of a Donna teenager.

Sheriff J.E. “Eddie” Guerra announced via Twitter that sheriff’s investigators had arrested 17-year-old Carlos Julian Contreras of Alamo for the shooting death of 18-year-old Genaro Isaiah Castillo, which is being investigated as a murder.

Castillo’s body was discovered Tuesday on a caliche road near a sugarcane field off of Valley View Road in the Donna Lakes area. Guerra said that his office received a 9-1-1 call at around 5:47 p.m. from a farmer reporting that one of his field workers found Castillo’s body.

Authorities estimated that Castillo died 10 to 15 minutes before the field worker found him.

Guerra said Castillo had been shot multiple times.

A motive for the killing has yet to be determined.

The official said Tuesday evening that investigators believe Castillo attended a high school with the Donna Independent School District.

Contreras will be arraigned on Thursday at 2 p.m.
