New York City police have identified the man found fatally injured under a mattress at a hotel blocks from the Empire State Building.

Police said Tuesday that 28-year-old Roderick Goodwin of Bridgeton, New Jersey, suffered trauma to the back of his head.

Officers were called to the Hilton Garden Inn on West 35th Street at around 4 a.m. Monday. Goodwin was pronounced dead at a hospital.

Investigators and medical examiners are working to determine how he died. No arrests have been made but the death is being treated as a crime.

A hotel manager hasn't immediately returned a call.

The 298-room hotel is near Herald Square and Penn Station in a part of midtown Manhattan bustling with both tourists and business travelers.
