Details are emerging about the armed man who allegedly breached a secure perimeter at President Donald Trump's Mar-a-Lago property before being fatally shot by law enforcement officials on Sunday, Feb. 22.

The Palm Beach County Sheriff's Office identified the man as Austin Tucker Martin, 21, from North Carolina. Martin was reported missing within the last few days, Reuters reported.

Martin was allegedly seen near the property's north gate at about 1:30 a.m. and was stopped by a Palm Beach County sheriff's deputy and two Secret Service agents. The president was in Washington during the incident and not at his Florida club.

Palm Beach County Sheriff Ric Bradshaw alleged that Martin was carrying a shotgun and a fuel can, and the officials ordered him to drop the items. Martin put the gas can down, but the sheriff said he "raised the shotgun to a shooting position" and authorities fired their weapons at him in response.

As more information is released, here's what we know about Martin.
