LAKESHIRE, Mo. — Police say the man fatally shot by an off-duty St. Louis police officer had been arguing with the cop on social media before the shooting.

Tyler Gebhard, 20, was killed Saturday after demanding entry to the officer's home and threw a planter through the glass door.

Gebhard, who had been dealing with a mental illness, knew the officer through a church connection, STL Today reports.

The two allegedly got into an argument on Facebook regarding Black Lives Matter right before the shooting.

The officer was at home with his wife, mother-in-law and two young children when someone began ringing the doorbell.  The officer's wife recognized Gebhard from the community and closed the door. KTVI reports Gebhard had been dealing with a mental illness.

St. Louis County Police Chief Jon Belmar said Gebhard went to the back of the house and threw a 50-pound concrete planter through a window to get into the home.

Family members say they heard the officer telling Gebhard to "get down" before shots were fired. Gebhard did not have a weapon on him.

Police have not identified the officer involved but say he is a three year veteran of the department.
