Authorities have announced that four people have been charged with the murder of an airport worker.

The incident happened back on March 13 around 7:11 a.m. at Isabella Avenue and University Place in Irvington.

According to police, Samuel Gbotoe, 62, was violently assaulted on his way home from work. Police say Gbotoe died three months later from the injuries.

An autopsy report in October determined the manner of death was homicide, and the cause of death was complications from blunt force trauma to the neck.

Surveillance video of the attack showed a large group chasing the victim. The investigation also revealed the group attacked others. Other arrests are possible.
