ROCHELLE PARK -- A Maywood man threatened police with a BB gun before police shot him, newly released police reports said.

An attorney working at a law office at 218 Route 17 North called police at about 3:27 a.m. on Dec. 14 to report that an occupied vehicle had been parked near the building entrance for several hours. The driver was Matthew Chaseman, of Maywood, police would later learn.

Rochelle Park Police officers Brian Cobb and Donna Porcaro were dispatched. Use-of-force reports say Cobb and Porcaro opened fire when Chaseman threatened them, both with a firearm and physically.

The recovered firearm turned out to be a BB gun with its orange tip painted over, Bergen County Prosecutor John L. Molinelli said at the time.

Rochelle Park Police and the Bergen County Prosecutor's Office both declined to elaborate on how Chaseman threatened the officers.

Chaseman crashed his green Toyota Camry sometime before parking in front of the office, a crash investigation report completed by Rochelle Park Police said. His Toyota Camry was traveling northbound on Route 17 and struck a curb on the ramp to East Passaic Street. The car ran off the road and struck a paver retaining wall on the lawn of 218 Route 17 North. It then drove over the grass onto East Passaic Street before turning into the office driveway and coming to a stop.

Chaseman has been charged with firearm possession and two counts of aggravated assault on a police officer. Chaseman was hospitalized with lower body injuries after the shooting and transferred to the Bergen County Jail over the holidays.

He was initially held on $250,000 bail, but a judge lowered bail to $100,000, court records show. Chaseman was still in jail as of Wednesday, jail records show.
