As CBS 2’s Mike Puccinelli reports, around 3:30 a.m. Wednesday, a man called police in South Bend and said he feared his mother was dead inside her home.

South Bend police went to the apartment and found the body of 42-year-old Deshone Caradine. She had been stabbed to death, police said.

Police continued to search for the suspect — identified as 44-year-old Manuel Clemon, also known as Manuel Scott — after finding the victim’s car on Chicago’s South Side, hours after the murder. Police said Clemon had a child with the victim. It was a different child who found Caradine’s body.

Police said Clemon is believed to be armed and dangerous. He is described as an African-American man, 5 feet 7 inches tall and approximately 200 pounds.

Caradine’s Ford Focus was stolen and authorities said it was found abandoned in the drive-up lane of the Highland Community Bank at 87th and Wood streets. Blood was clearly visible on the steering wheel and elsewhere inside the vehicle.

After securing the scene, a team of police officers descended on a nearby house on the 8700 block of South Winchester Avenue. With their guns drawn, officers surrounded the house and a team entered through the back door.

The homeowners showed up a short time later, but were not allowed inside. They declined to speak to reporters.

After spending about a half hour inside the home, police then went to the Hogan Motel at 89th Street and Ashland Avenue, where they found the keys for the Ford Focus and a set of bloody clothes.
