A man out on bond for a gun possession charge was arrested Tuesday in the shooting death of HPD Sgt. Sean Rios, as investigators continue to piece together what precipitated the deadly gun battle on Houston's northside. Robert Soliz, 24, was taken into custody on the Katy Freeway and now faces a murder charge, police said. Case records were not yet available Tuesday night. Police also are searching for a second man, only identified as a person of interest, who fled the shooting scene in a black pickup. Newly released surveillance video shows that person talking to Soliz shortly after the killing. Soliz is accused of shooting Rios around 1:30 p.m. Monday near the Interstate 45 service road at Stuebner Airline. Rios was pronounced dead at a nearby motel, where he sought help.
