STANTON, Del. (CBS) — A man and pregnant woman were shot and killed while they were inside a car near Wilmington, early Thursday morning. Now, police are desperately searching for clues in the case.

New Castle County police say they discovered the bodies of two people with gunshot wounds inside a vehicle at the intersection Kiamensi Road and Rothwell Drive in Stanton just before 2 a.m. Initially, the caller reported a single-car crash involving a green Honda, but when officers arrived, they found two people dead.

Police say 30-year-old Isabel Cooper, who was seven months pregnant, and 34-year-old Thessonlonis Berry were each shot and killed. Cooper’s fetus also died in the shooting.

Their car slammed into a curb right by Roy Dickens’ home, but he remained asleep, not hearing any of it.

“Nothing, absolutely nothing,” said Dickens.

Police have not yet said how the victims know each other or if they were shot here or at another location. Detectives were combing for clues through tall grass by the crash sight. Eventually, some of the grass had to be cut to give detectives a better view. That’s when at least one item was found.

It also looked like the car had a cracked window.

Police do not have any information on a suspect.

A $10,000 reward is being offered for anyone who provides information leading to the arrest and conviction of those responsible for the double murder.

Anyone with information on the investigation is asked to call police at 302-395-8110 or 302-573-2800.
