Authorities detail chilling tactics of Baton Rouge shooter Gavin Long, who was killed by SWAT team from 100 yards away: ‘It was a hell of a shot’

Gavin Long moved “tactically” as he killed police officers, authorities said.

The Baton Rouge shooter was armed to the teeth and “extremely accurate” in his ambush that killed three cops and wounded three more.

Gavin Long, 29, executed three cops in cold blood before being gunned down by a sharp-shooting member of the Baton Rouge Police Department SWAT team that took him out from 100 yards away.

The chilling sequence of events began when Long, a former Marine from Kansas City, Mo., closed in on a car wash, seeking to sneak up on a police officer.

“He came in here from somewhere else to do harm to our community, and specifically to our law enforcement community,” Louisiana Gov. John Bel Edwards said.

As Long snuck around, using “tactical” movements reflecting his training as a Marine, he ignored civilians, Col. Mike Edmonson, of the Louisiana State Police said.

One of those witnesses called 911, telling the operator of “a dude with a rifle.”

That call lead to the bloody confrontation with cops that Long was after.

At a convenience store near the car wash, Long opened fire on two Baton Rouge police officers and one East Baton Rouge Sheriff’s deputy using an IWR Tavor SAR 5.56 rifle with a shoulder strap.

“Clearly he was in shape,” Edmonson said.

“He was articulate in all manners of engagement.”
