BERKELEY, MO (KTVI) – Berkeley Mayor Theodore Hoskins believes the evidence is clear. He believes the shooting death of 18-year-old Antonio Martin was justified. He says Martin pointed a weapon at a Berkeley officer before the officer fired three shots.

"They're out here protecting us every day and sometimes it comes to the point where they have to take necessary action," said Hoskins. "That's what occurred."

Police released surveillance video from the gas station where Martin was shot and killed. Police say there was a report of a robbery. Police say the video shows Martin raising his harm and pointing a weapon at the officer. Police released separate photos of the weapon they say Martin was holding.

Hoskins says Berkeley will conduct its own investigation and plans on releasing the findings of that investigation in about one week.​
