ST. LOUIS — An off-duty cop shot and killed a 20-year-old student who broke into his house on Saturday after arguing with him about Black Lives Matter online. <br /> <br />Tyler Gebhard threw a 50-pound concrete planter through a back window at the unidentified cop’s home when the officer’s wife refused to let him in. <br /> <br />Gebhard was shot twice in the chest after ignoring warnings to “get down”, the St. Louis Post-Dispatch reported, citing police. <br /> <br />Gebhard had bipolar disorder and would sometimes stop taking his medication, his uncle told the Post-Dispatch. <br /> <br />The student, who was a Black Lives Matter supporter, knew the police officer through a church connection. The two men argued about the activist movement on Facebook. <br /> <br />Members of the police officer’s family, including his wife and two young children, hid in an upstairs bedroom when Gebhard came to the house. <br /> <br />Police said Gebhard’s actions gave the off-duty cop little choice but to shoot him. <br /> <br />The officer is a three-year veteran of the force. He was placed on administrative leave pending an investigation.
