A serial rapist serving several life sentences in a maximum-security state prison has died in the hospital after being assaulted by another inmate, Maryland State Police said Wednesday.
Michael Armstead, 53, was assaulted Nov. 27 at the North Branch Correctional Institution in Allegany County as inmates were on their way to the dining hall, and died at Bon Secours Hospital in Baltimore on Jan. 9.
State police did not release the name of the suspect who allegedly assaulted Armstead, but said charges are pending. The suspect is also serving a life sentence, police said.
State police said the Office of the Chief Medical Examiner in Baltimore ruled Armstead's death a homicide caused by a head injury.
Armstead was found guilty in the early 1990s of serial home-invasion rapes in Anne Arundel and Howard counties and was serving six life sentences.
