Scottsdale, AZ – The former National Football League (NFL) player who was arrested at a Scottsdale funeral home on Monday got upset when employees denied his unusual request.

Former Buffalo Bill Richie Incognito, 35, told Messinger Pinnacle Peak Mortuary employees who were assisting in planning his father’s funeral that he wanted his father’s head cut off for research purposes, according to the Rochester Democrat & Chronicle.

When employees refused his request, Incognito walked around the funeral home punching caskets and throwing things, according to a police report that detailed his erratic behavior.

Initially, Incognito was supposed to sign cremation papers before he had his tantrum.

Afterwards, he walked calmly into one of the employee’s offices and said he wanted to buy flowers for the funeral and gave them a credit card, the Rochester Democrat & Chronicle reported.

He eventually signed the cremation paperwork, but then he changed his mind and told funeral home employees that he wanted his father to be buried.

Employees showed Incognito burial options, including a military casket. The football player said he wanted the military casket at first, but then he picked up an urn and slammed it down on top of the casket, the Rochester Democrat & Chronicle reported.

Incognito then began to throw pamphlets and patches from inside the casket around the room, and broke down crying while asking for his father.

Witnesses told TMZ that Incognito was “violent, incoherent, and emotional.”

Employee Michael Wells told police that when he was sitting alone with the football player after his meltdown, Incognito formed a gun with his fingers and pointed it at him.

Then he told Wells that he had guns in his truck and offered to show them to him.

Wells, shaken by the incident, told TMZ he had thought that Incognito was going to kill him and so he ran for a secure room and locked himself inside.

When police arrived, they arrested Incognito at gunpoint.

Officers told TMZ that Incognito "appeared to lack concentration and was unable to maintain a coherent thought, rather, he appeared to ramble about numerous things that did not correlate."

His mood swung back and forth from calm and respectful to terribly angry, police said.

Officers obtained a search warrant for the former Pro Bowler’s car and found a Glock 17 9mm handgun, a Glock 35 .40-caliber handgun, three rifles, and four magazines inside Incognito’s Ford Raptor, the Rochester Democrat & Chronicle reported.

Incognito was charged with disorderly conduct and making threats, ESPN reported.

Incognito has been in the news several times in recent years for off-the-field incidents.

The 12-year veteran of the NFL was selected to play in four Pro Bowls during his professional football career.

He was released from the Buffalo Bills in May, the same month he was involved in a disturbance at a Boca Raton gym.

Police said that Incognito allegedly threw a tennis ball, and then a dumbbell, at another man for no apparent reason, according to TMZ.

The victim told TMZ that Incognito was rambling about the government and yelling at the man to “get off my f–king playground."

Incognito left with police but wasn’t arrested right away because police believed Incognito was in an “altered, paranoid” state.

ESPN reported that Incognito believed that “ordinary citizens were government officials that were tracking and recording him” when he was taken into custody.

He was detained and put under involuntary psychiatric evaluation, according to USA Today.

Afterward, Incognito told the Associated Press that he was back in Arizona after spending three days in a mental hospital.

Then he told ESPN that the Minnesota Vikings and Seattle Seahawks had contacted him about playing in the upcoming NFL season.

However, Minnesota Coach Mike Zimmer said that was “totally false.”

Incognito called Zimmer a “liar” in a profanity-filled tirade on Twitter, but later apologized, according to ESPN.

The former NFL lineman was suspended by the Miami Dolphins in 2013 amidst allegations that he had bullied teammate Jonathan Martin, according to USA Today. A report paid for by the NFL identified Incognito as one of three players who had “engaged in a pattern of harassment” of Martin.
