An armed murder suspect was shot and killed Thursday after leading police on a freeway chase during morning rush hour, authorities said.

"During the exchange of gunfire with the officers, the suspect was struck and pronounced dead at the scene," said Torrance police Officer Dave Crespin.

The suspect's black Nissan Maxima was struck by a pursuing police car and spun out on a transition road from the northbound Interstate 405 to the southbound Harbor Freeway in the Carson area of south Los Angeles County.

"It was a dangerous situation. He was obviously trying to evade arrest. He was swerving in and out of traffic," Crespin said.

The suspect's car ended up at a stop nose-to-nose with a police car. The gunfire erupted when a police armored vehicle moved in from behind to pin the Nissan.

In a scene broadcast live by TV news helicopters, gunfire that appeared to come from inside the Nissan blew its rear window outward and struck the armored vehicle, and police fired into the car. The man was lying in the car's back seat area when officers broke into the Nissan.

The unidentified man was sought in the fatal shooting of a man Wednesday night in Torrance.

Officers located the suspect Thursday morning just east of Torrance, and a pursuit ensued.

Police could not confirm reports that the suspect may have tossed a weapon from the vehicle at one point during the chase that reached 90 mph.
