Neighbor films astonishing shootout between Charlotte cops and gunmen that left ... trends now

A neighbor caught the terrifying shootout between Charlotte police and two gunmen in a shootout that left four officers dead and another four injured.

A livestream shared by Saing Chhoeun on Facebook shows two heavily-armed cops taking cover behind a vehicle as they engage in the gun battle on Monday.

The video begins with the terrified neighbor seemingly locked outside his house and asking someone to let him in. 

The officers repeatedly ask the neighbor to go inside the home, but he informs them he can't because he does not have the keys.

The shooting happened as four officers were serving a warrant for felon Terry Clark Hughes, who was wanted for possessing a firearm and shot dead in the gun battle. 

Samuel 'Sam' Polche, William 'Alden' Elliot and Charlotte police officer Joshua Eyer died Monday following the horror shooting as they tried to serve warrant. Both Polche and Elliot were North Carolina Department of Adult Corrections officers working with the US Marshal's office.

The US Marshal killed in the attack has not been named.

Some of the officers who rushed to the Charlotte neighborhood to rescue the first wave of downed officers were wounded as a second shooter began firing on them after they killed the wanted man, Charlotte-Mecklenburg Police Chief Johnny Jennings said.

'When [officers] approached Hughes they were met by gunfire and returned the gunfire, striking Hughes, who was found deceased in a yard', Jennings said.

Officers then received 'additional gunfire' from within the residence, but it is not yet clear whose bullets struck which officers, and how many cops were hit overall.
