RICHLAND, Wash. - A Richland Police Officer was driving westbound on SR 240 at Columbia Park Trail Wednesday night about 11:30, when he saw a 2005 Kia next to him with a burnt out headlight. The vehicle passed him and he recognized the license plate and car from a call earlier in his shift. The Officer tried to stop the car but the driver sped up. The officer followed the car on I-182 into Pasco where the suspect reached speeds of 100 mph to 115 mph. The driver took the Rd. 100 exit but was going too fast and spun out. The driver got out of the car and ran. A passenger also got out but was detained for questioning and later released. The suspect was not found, but investigators say 19 year old Lamark Walker was likely driving the car. He's black, 5'8", 140 lbs. Anyone with information on Walker's whereabouts or this investigation is asked to call the Richland Police at 628-0333.
