The Connecticut Office of the Inspector General released its preliminary report, along with body camera footage, of a fatal police-involved shooting Monday in Bridgeport.

The report and video mainly back up what police originally said - that they got a call, there was a fight and that someone with a gun was in a black Chevy Tahoe.

They say they tracked that truck down - and told the man in the passenger's seat they had to pat him down to look for a gun.

An officer is heard telling the man, now identified as Dyshan Best, "if you got nothing and it's quick, then we'll let you go."

Best denies having a gun, before running off, appearing to reach for something out of the back of his belt, before starting the chase with a liquor bottle in one hand, and what looks like a gun in the other.

Officers are heard yelling for Best to stop running and firing a taser at him, as he leads them up a driveway on Kossuth Street.

That's where officers say they first saw the gun and opened fire. Police say they recovered a handgun on the ground next to him.

After looking at the report and video, Best's family says they're not convinced officers needed to shoot him.

"This is sick," said Cecilia Jessie, Best's sister. "He was a good guy and he did not deserve to have this happen to him the way it did."

"I believe my brother was scared," added Leonard Best. "When I see my brother get out of the car, I just seen it on his face. I believe that's why he run."

The family's lawyer, Darnell Crosland, also argued that a possible gun possession charge isn't enough to pull the trigger.

"This is what you get a warrant for, you do an investigation, then you arrest people accordingly. You don't become the judge, jury, executioner," he said.

"What I viewed on the video, as I know use of force, as I know training, appears to be in line with use of force and the use of force policy set forth," said Bridgeport Police Chief Roderick Porter.

News 12 asked the chief exactly what the training and protocol are for a situation like that, but he said he couldn't get into details.

"The ultimate decision will come from the Inspector General's Office, and they will decide if this was a justified or non-justified shooting," Porter said.

The officer who fired the shots is currently on paid administrative leave until the investigation is over, which is standard protocol.

The family says they are planning more prayer vigils and protests over the next few days.
