Police seek clues in neighborhood killings

Authorities, residents worry whether two mother-daughter homicides in Prince George's are work of a serial killer

Detectives are also investigating the theft of the vehicle in which the Dewitts' bodies were found, and a burglary at the home of the car's owner, in the 10800 block of Woodlawn Blvd. Police said they think the car key was the only item stolen in the Feb. 28 burglary.

Police think the burglar returned Monday and took the car.

According to sources, the resident called police from her driveway Monday at 3:39 a.m., reporting that she and her boyfriend had returned home to find her Nissan Maxima missing. Ten minutes later, as the woman spoke to a 911 operator, she shrieked. According to two sources who have heard a tape of the conversation, she said someone was speeding by her house - in her car.

Nine minutes later, less than three blocks away, firefighters and police found her car ablaze in the driveway of a vacant home in a nearby cul-de-sac. A four-hour search of nearby woods and homes turned up no suspects.

Investigators think the last time the Dewitts were seen alive was nearly 24 hours earlier, between 1 a.m. and 3 a.m. Sunday, when a neighbor saw Ebony Dewitt return home, said Maj. Andy Ellis, chief spokesman for the county Police Department.
