UPPER MARLBORO, Md. (AP) — A D.C. police officer charged with trying to kill his wife is scheduled to go on trial in Prince George’s County.

Samson Lawrence III is scheduled for trial Tuesday and faces charges including attempted murder.

Prosecutors say that on Nov. 24, 2013, Lawrence was attempting to hang a projection television at his home in Accokeek when he became angry with his wife because she said she didn’t know where the screws to hang the projector were.

Prosecutors say Lawrence then grabbed a can of Lysol and began spraying it in his wife’s face. Prosecutors say he beat her with a metal light post and threatened her with knives when she tried to call 911.
