Duriso said the victim and the alleged shooter knew each other, but police do not know a motive for the killing at this time. Authorities on Monday said they had a “strong lead” in the fatal shooting and had put information out on the suspect to alert other agencies.

According to information from Bexar County Central Magistrate, Martinez-Martinez was arrested at 2 p.m. Monday and is being held without bond.

Justice of the Peace Ben Collins Sr. said Martinez-Martinez is a flight risk and was headed toward Mexico. The alleged suspect must undergo an extradition hearing before being transported back to Jefferson County, at which time a bond will be set, Collins said.

The shooting was reported just after midnight Monday outside a home in the 1900 block of Green Avenue.

The victim was found unresponsive in the driveway and had suffered a gunshot wound, Collins said.

An autopsy has been ordered.
