The suspect was identified as 24-year-old Timothy Johnson, described as being 6 feet 2 inches tall, weighing about 170 pounds with a dark complexion and a closely shaved head.
Detectives say Johnson reportedly entered eChaps Computers and More at 2007 W. Avenue K on Friday, shot and killed store owner Reed Lewis Keith and left with stolen electronics in hand.
Johnson reportedly fled in a black, 1980s model four-door car driven by an accomplice. Investigators said Johnson was wearing a black hooded sweatshirt and a ski mask at the time of the robbery.
Hours after the shooting at about 8 p.m., a barricade situation was reported in the 43000 block of Grange Street. The standoff was believed to be related to the shooting, but the suspect was gone by the time SWAT entered the place early Saturday morning.
Officials said most of the stolen property from the computer store was recovered at a nearby residence.
