This is part two of the Wild Chase in Houston today. Houston Texas 4-6-12 The pursuit began after a security guard at a Walmart noticed a suspicious person possibly trying to break into a vehicle. That guard alerted HPD but the suspect took off in his own vehicle, the Trailblazer, and fled the scene. The chase then started after other drivers on Interstate 45 saw the suspect driving erratically and called 911. source: KTRK
