Randy Allen Segura, 19, was arrested and charged with capital murder Tuesday in the Monday night killing of Otis James in his home in the 100 block of South 4th Street near Avenue C.
James' neighbors discovered him dead when they went to check on him. He was unresponsive, sitting in a chair with multiple gunshot wounds and pronounced dead at the scene.
Investigators are not sure if James knew Segura. There were no signs of forced entry and James' truck was missing.
A truck, matching the description of James was later found on the East Freeway near Jacinto Port Boulevard.
Segura is due in court April 11.
