BELLEVILLE - The family of a 40-year-old man who was shot two dozen times by police trying to serve a restraining order wants answers about what happened.

Dante Cespedes's wife had gone to the police early Tuesday asking for a restraining order against her husband, whom she said was physically abusing her and their children.

Police say when four officers arrived at the Lake Street apartment, Cespedes lunged at them, armed with two knives. Three of the officers opened fire, killing him.

Family told News 12 New Jersey that Cespedes, a chef at a Manhattan hotel, had been drinking that night and arguing with his wife Judy.

Acting Essex County Prosecutor Carolyn Murray says the incident is under investigation.

"The investigation will not look at just the number of shots. It will look at the time period, the proximity of the defendant to the officers, any number of factors, the directionality, the length of time over which these shots were fired," Murray says.

Prosecutors say 30 shots were fired, striking Cespedes 24 times.

Investigators are waiting on results of an autopsy and toxicology report on Cespedes.
