WARREN, Maine (AP) The father of a man who died at a Maine State Prison in 2018 has alleged in a wrongful death lawsuit that his son’s health care provider failed to properly treat him.

According to the complaint, 51-year-old Andrew Leighton sought medical attention five times between July 31 and when he was found unresponsive in his cell on Oct. 1.

Bangor Daily News reports that Thomas Leighton is suing Wellpath, formerly known as Correct Care Solutions. The lawsuit alleges that Wellpath was negligent in treating Andrew Leighton’s infection.

A spokesperson for Wellpath did not immediately respond to a request to comment.
