Hedwig Police Sgt. Marvin Collins said he believes Bernard was beaten and stabbed."Very brutal scene," Collins said.Collins said there are indications that Bernard fought back based on her injuries. According to investigators, she was stabbed multiple times and suffered a punctured lung.The victim's son told investigators he last spoke to his mother around 2:15 p.m. on Sunday.The vehicle was found in the 2100 block of Van Cleve Street, and was taken by HPD for testing.Investigators said the area is a "common place" for people to abandon cars, and that the keys to the vehicle were found about 100 feet from the roadway.Bernard apparently kept very detailed notes and followed a specific routine, always locking her doors and never answering the door after dark.These facts have led police to believe she may have known her attacker. Police said parts of the home were ransacked and that the suspect spent a lot of time in the home.Her wallet and Cadillac were missing when her body was found, but again, police have since recovered the stolen car.Investigators have canvassed the neighborhood for a second time Tuesday.
