EAST ORANGE - The death of a 90-year-old man found in his Essex County apartment this week has been ruled a homicide.

Essex County prosecutors announced the finding Wednesday. They say an autopsy determined that Henry Boyd died of compression of the throat and a fracture of the larynx.

The East Orange man was unresponsive when a relative found him on Tuesday. He was pronounced dead at the scene a short time later.

Prosecutors have declined to release further details on the death, citing the ongoing investigation.

The county's major crimes task force is leading the probe into Boyd's death.

Anyone with information is asked to contact the Essex County Prosecutor’s Office at 1-877-TIPS-4EC or 1-877-847-7432.
