Recently-retired offensive lineman Richie Incognito was arrested on Monday in a Scottsdale, Ariz. funeral home, after employees said he threatened to shoot them and was disruptive.

Incognito and others had gathered after the death of Incognito’s father on Saturday.

But there are more details about Incognito’s behavior coming from the police report.

Wanted to have father’s head cut off for research

Stevie Johnson of the Rochester Democrat and Chronicle got a copy of the police report; in it is more information about what allegedly happened at Messinger Pinnacle Peak Mortuary.

Employees told Scottsdale police that Incognito wanted his father’s head cut off for research purposes, and that he had walked through the funeral home punching caskets and throwing objects.

It’s not clear what kind of research Incognito wanted done on his father’s head; in his tweet announcing his father’s death, Incognito said he had been an Army airborne ranger, so maybe he wanted to have his father’s brain studied for effects of CTE or other traumatic brain injury. (Incognito also used the name Richard Dominick Dejasa as his father’s name, but past stories refer to him as Richie Incognito Sr.)

Witnesses told police that Incognito initially did not want to sign cremation papers, and that’s when he began punching caskets and throwing things. He apparently made himself comfortable in the office of one of the employees, then said he wanted to buy flowers for the funeral service and everything they had, offering his credit card.

He signed the cremation papers, but then witnesses said he changed his mind, wanting his father buried instead. He was shown a military casket, indicated he wanted it, then slammed an urn on top of the casket.

Behavior was erratic

Incognito allegedly threw pamphlets from inside the casket, then broke down into tears, asking for his father. Alone with funeral home employee Michael Wells, Wells alleged that Incognito made a gun with his fingers, pointed it at him and said he had guns in his truck.

Wells, shaken, believed Incognito was going to kill him.

After obtaining a search warrant, police recovered a silencer, two Glock handguns, three rifles and four magazines from Incognito’s truck. The weapons were impounded.

This is at least the second incident of violent, threatening behavior from Incognito in recent months. In May, he threw a tennis ball and dumbbell at a man in a Florida gym, screaming at him. Incognito was taken into custody for a psychiatric exam and released.
