SPOKANE, Wash. -

Jason Hart, the Nine Mile Falls man accused of strangling his girlfriend and putting her body in a tub of acid pleaded not guilty to her murder Tuesday.

Hart, 27, had only been dating Regan Jolley for a few weeks prior to the murder.

His trial for Jolley's murder is set for August 12.
