The Fairview Township man charged with bludgeoning his wife and stepdaughter to death will spend the rest of his life behind bars.

Regis Brown, 59, pled guilty Wednesday morning to first-degree murder in the death of his wife Michelle Brown, 53, and third-degree murder in the death of his stepdaughter Tammy Greenawalt, 35. He was then sentenced to life without parole plus 40 years.

Brown and Greenawalt were found dead inside the family's Fairview Township home on West Ridge Road back in March. According to investigators, Brown bludgeoned his wife to death and rolled her body up in a carpet. They say he then stabbed his stepdaughter. Brown's also accused of tying up his 14-year-old granddaughter in a bedroom for most of that weekend. That teenager alerted authorities at school the following Monday.

Erie News Now has learned that Brown is still being investigated in connection to a cold case murder near New Castle, PA from 1988. Troopers say they are still investigating and Brown is still a person of interest in that case. State Police also tell us Brown was a person of interest in a cold case in Corry, but they weren't able to connect him to the murder. That Corry case has since been closed.
