MONTGOMERY COUNTY, Pa. (CBS) — An 86-year-old woman in Montgomery County was killed after a car came barreling into her bedroom early Friday morning.

It happened just after midnight along the Harleysville Pike in Franconia Township.

Neighbor’s like Andy Tawny heard the impact of the crash, from three houses away.

“It was a giant explosion,” said Tawny as he described what his wife and he heard.

Authorities say the driver of 1995 Toyota ran off the Harleysville Pike and ran through a mail box and the lawns of three houses, before crashing into the 86-year-old’s bedroom.

Police say the woman, identified as Mary Ann Lambert, was asleep at the time of the crash.

“I feel so sorry for the family. My wife and I have been praying for the family,” Tawny added.

Investigators with the Montgomery County District Attorney’s Office and the Franconia Township Police Department are still trying to piece together what caused the 21-year-old driver to veer off the Harleysville Pike and into the home.

Eyewitness News spoke to the family of Mary Ann Lambert, briefly over the phone, and the family said they have serious concerns that the 21-year-old driver may have been under the influence.

“Lab tests need to be done in this case, to get answers as to why, but this is another tragic incident where someone has turned a vehicle into a lethal weapon. You can expect more coming,” said Montgomery County District Attorney Kevin Steele.
