Authorities are seeking the public's help and offering up to $5,000 for information that leads to the arrest of the two suspects accused of shooting and killing a tire shop owner in southwest Houston in March.

Houston police said Bobby Garcia, 38, stopped at the convenience store next door to buy drinks for his shop on Almeda. On his way out, he saw two men stealing from a Lexus. Garcia and the convenience store owner, who owns the Lexus, stepped in. A gunman opened fire. Bullets grazed the store owner, and Garcia was killed.

"I want justice for my son, because he didn't deserve this," said Rose Garcia, the victim's mother.
