Berwyn police, still searching for the driver of an SUV that crashed into a train platform on March 3, killing a 58-year-old Riverside woman, have intensified their efforts to locate the owner of the vehicle.

On Tuesday, Berwyn police executed a search warrant at the Riverside condominium of Stephen J. Pocina, who is the registered owner of the 2004 Range Rover found at the scene of the early-morning incident, which left ticket agent Kathleen Talmage dead.

Tom Stanton, spokesman for the Cook County State’s Attorney, confirmed that Berwyn police obtained a warrant to search the condo at 12 E. Quincy St. on Tuesday. The warrant was executed by Berwyn police that afternoon.

Blood found inside the vehicle by Berwyn police has already undergone DNA testing. Meanwhile, Berwyn Police Chief William Kushner confirmed that his department was granted a subpoena to collect DNA evidence from Pocina’s mother. Police delivered the sample to a laboratory in Rockford on Wednesday and are awaiting the results.

Kushner said he did not know how long the department would have to wait until the results of the DNA test would be returned.

Police have not been able to determine who was driving the vehicle at the time of the crash. According to an eye-witness account, at 5:45 a.m. on March 3 the SUV sped westbound on Windsor Avenue, jumped an earth berm and slammed into the station building at 7135 W. Windsor Ave. The driver staggered out of the vehicle and fled on foot before police arrived.

Talmage, who was inside the station at the time, was critically injured by impact of the collision and died shortly thereafter at MacNeal Hospital.

Police reported making contact with the driver or an agent of the driver in the hours after the crash. Since that time, however, police have had no contact with the driver. Police have also been unable to make any contact with the vehicle’s owner, despite police attempts to do so in the hours and days following the crash.
