Connecticut's Office of the Inspector General has ruled that three Stamford police officers were justified when they opened fire during a lengthy and violent standoff with an armed homeowner who ended up taking his own life.

The inspector general's 49-page final report on the incident was released Friday and includes new details and pictures from the dramatic confrontation. It happened Dec. 2 after a state marshal arrived at Jed Parkington's home on Oaklawn Avenue to carry out a foreclosure-related eviction. According to investigators, Parkington answered the door wearing a military-style uniform with Nazi insignia and appeared to have devices on his belt that were suspected to be explosives. He warned the marshal to take his wife somewhere safe because "this is not going to end well."

Parkington barricaded himself inside, fortified windows with cinder blocks and refused repeated orders to surrender, the report said. Negotiators spent hours trying to end things peacefully, but when efforts proved unsuccessful, two armored police trucks moved in. That's when Parkington threw an improvised explosive device at one before unloading a barrage of bullets that pierced the vehicles windshields. The report said he also fired at police drones and shot at nearby propane tanks before ultimately turning the gun on himself. Three officers returned fire during the standoff. Sgt. Matthew Romano, positioned on a nearby deck as a sniper, fired two rounds at Parkington's fortified position. Lt. Jose Alvarez fired at least 84 rifle rounds and Capt. Chris Baker fired at least 27 rounds from inside an armored vehicle in an effort to stop what police described as an ongoing deadly threat. None of the officers' shots struck Parkington. He was later found dead with a self-inflicted gunshot would to the head.

A search of the home after found Molotov cocktails, grenades and other explosive devices, along with an even more disturbing discovery--the body of Parkington's tenant, 79-year-old Carmine Boccuzzi. Police later determined Parkington killed Boccuzzi because Boccuzzi wouldn't move out and Parkington needed him gone to carry out his planned confrontation with police.

In his analysis, Inspector General Eliot Prescott found Stamford police made extensive efforts to de-escalate the crisis before resorting to deadly force. The report notes negotiators spent hours talking with Parkington, officers repeatedly ordered him to surrender, and police deployed less-lethal tactics including flash-bang devices, pepper-agent rounds and drones. Prescott concluded that Parkington posed an ongoing deadly threat by firing repeatedly at officers, armored vehicles and other targets in the neighborhood. As a result, he found the actions of Baker, Alvarez and Romano were objectively reasonable and legally justified under Connecticut law. The inspector general closed the case, finding no basis for further action against any of the officers involved.
