John O’Keefe, a 16-year veteran of the Boston Police Department, was found dead outside of a home in Canton, Massachusetts in the early hours of Saturday, January 29.

O'Keefe was discovered Saturday morning outside a Canton residence on Fairview Road, a spokesperson for Norfolk District Attorney's Office told The Boston Globe.

When O'Keefe's body was found, a powerful winter storm had blanketed the area in more than 20 inches of snow.

O'Keefe “appeared to have been in the cold for some period and was transported to Good Samaritan Hospital,” where he was pronounced dead.

“The circumstances of his death are still under investigation and do not appear to be definitively known," the spokesperson said.

The Office of the Chief Medical Examiner in Massachusetts is expected to conduct an autopsy on O'Keefe's body today, January 31, to determine the cause and manner of O'Keefe's death.
