Convicted killer dies in prison

WARREN — A man who has spent more than half his life in prison for the murder of two Trumbull County men has died in prison, according to a report from the Trumbull County Prosecutor’s Office Tuesday.

Henry G. Rockwell, 77, died Monday at the Ohio Department of Corrections Medical Center, according to the report.

Rockwell was sentenced to 15 years to life in prison for the deaths of Seymour Gillman and Frank Mancinelli, who were shot and killed July 17, 1981. Their bodies were placed in the trunk of a silver Cadillac Seville and set on fire, according to information in a packet Trumbull County Prosecutor Dennis Watkins sent to the Ohio Parole Board opposing Rockwell’s release. The car was left ablaze on state Route 82 where Howland firefighters discovered the bodies.

Rockwell was 38 at the time of his sentencing and had served 39 years in prison, according to state prison officials.
