What We Know About the Charlotte Shooting That Killed 4 Officers

Eight law enforcement officers were shot Monday, four of them fatally, in what the local police chief described as possibly the worst such incident in the Charlotte, North Carolina, area. "I can't remember an incident where three law enforcement officers were killed in the same incident, as well as one in critical condition and additional (officers) that were shot and injured," Charlotte-Mecklenburg Police Chief Johnny Jennings said before the fourth victim died at a hospital. What we know so far:

• 'A lot of questions': "We still have a lot to uncover, a lot of questions that are not answered right now," Jennings said, per CNN. What is clear is that members of the US Marshals Fugitive Task Force were serving a warrant for possession of a firearm by a convicted felon when the shooting began.

• How it unfolded: Task force members were met with gunfire, which then prompted a SWAT team to respond, Newsweek reports. According to the AP, as the second group of law enforcement came onto the scene, the wanted man was killed by officers, but a second shooter opened fire from inside the home, hitting more officers. After a three-hour standoff, armored vehicles ripped open the home. A woman and a 17-year-old male found inside were being questioned by police.
• Who was killed: Three of the victims have been identified: Charlotte-Mecklenburg police officer Joshua Eyer, who is survived by a wife and a 3-year-old son; and Sam Poloche and Alden Elliott, 14-year veterans of North Carolina's Department of Adult Correction. Poloche is survived by a wife and two children, and Elliott by a wife and child. The fourth victim, a US Marshal, has not yet been identified.
