A 56-year-old man shot and killed his 47-year-old male relative at a business Tuesday morning on the East Side before he turned the gun on himself, police said.

Police said the gunman showed up to work late at JTM Transport and entered the victim’s office around 11 a.m. in the 7300 block of Interstate 10 East and shot him several times. The victim was taken to a hospital, where he died.

The gunman fled the scene and was found several minutes later slumped in his vehicle with a self-inflicted gunshot wound to the head outside a Family Dollar store at 5120 N. Foster Rd., police said.

Both men worked at the business and had been involved in an ongoing workplace issue for several weeks, police said.

A family member told KSAT on Wednesday the two men are bothers, but police have yet to confirm their relationship.

A man who spoke with KSAT at the Family Dollar said the victim owned the company where the shooting occurred.
