Radnor police said Marlton, N.J., residents Ryan Letchford, 21, and Jeffrey Olsen, 22, left a party early Saturday and entered Constable Mike Connor's van, which had been in the parking lot of the condominium where the party was located, the Philadelphia Daily News reported Monday.

Police said a friend found them in the van after they failed to return to the party and called 911 because he was unable to free them. Police contacted Connor, who said he must have left a door unlocked because there was no sign of forced entry. "I came down and unlocked the doors, and 'Dumb and Dumber' pranced out of the van," Connor said. "They looked a little embarrassed." Connor said the men had been smoking cigarettes and spitting while inside the vehicle. Cigarette butts and "a large amount of saliva" were in the van, police said.
