CHULA VISTA (CNS) - A man was found dead inside a motorhome parked along a Chula Vista street and police are working Monday to determine how he died.

Officers conducting a welfare check on the man, who was said to be unresponsive, forced their way into the motorhome parked in the 500 block of C Street near Broadway and found his body shortly after 8:30 p.m. Sunday, according to a Chula Vista police statement. He was pronounced dead at the scene.
