Missouri teenager Mike Brown was killed Saturday when he was shot Saturday by Ferguson, Mo. police.

Here are more details about the incident from the St. Louis Post-Dispatch:

St. Louis County Police Chief Jon Belmar said one shot was fired by the officer’s gun inside the car during the struggle, and that the officer fired multiple times at Michael Brown, 18, as he ran away.

He said the shots that hit Brown were “more than just a couple but I don’t think it was many more than that.” He said an autopsy was pending and that a toxicology test would take as long as six weeks to determine whether Brown had alcohol or drugs in his system.

Angered over the incident, many took to Twitter to call for justice, using the hashtag #JusticeForMikeBrown.
