METHUEN — A Lowell woman who was killed when her car hit a house early Friday morning was not wearing a seat belt and was alone in the vehicle, police said.

Police said that at 2:36 a.m. Friday, local police officers, firefighters and other rescue workers responded to Riverside Drive for a report of a car crashing into a home.

When they arrived, rescue workers treated the driver and officers began to investigate.

Police said the initial investigation showed that a 2010 Honda sedan was traveling west on Riverside Drive. For an unknown reason, the Honda went off the road and crashed into the front of a house at 1058 Riverside Drive, police said.

The driver of the Honda — Justice Johnson, 23, of Lowell — was taken to Lawrence General Hospital where she died, police said.

Police Capt. Randy Haggar said the victim was not wearing a seat belt, but was not thrown from the vehicle. He said the car's multiple air bags did deploy and that the car is registered to the woman's aunt.

"She went head-on into the home's cement foundation and actually broke the foundation," Haggar said. "I've never seen anything like it."

Haggar said the preliminary results of an investigation showed there were some tire marks on the ground. He said investigators are trying to determine why the woman drove off the road.

"It could be environmental, although the road was dry when I got there,'' Haggar said. "But we're also looking at mechanical issues with the car and we're also looking at the operator to see if there was medical issue or if there could have been intoxication or that she fell asleep. We're looking at all those factors and the state medical examiner's office will be conducting toxicology tests, although we probably won't have the results for several months."

Haggar said the victim's family was notified after the crash, and that the victim's mother went to the hospital to identify the victim. 

Methuen Police and the Massachusetts State Police are investigating the crash.
