Preliminary investigation has shown that Phillips, his girlfriend and Estok were inside Phillips’ home early Wednesday when it is believed Estok was shot.

His girlfriend told police that after Phillips found Estok, who is also her aunt, he pointed a gun at her and threatened to kill her. She said she wasn’t allowed to call 911 initially, but was later allowed to by Phillips after agreeing to lie about the circumstances of Estok’s death.

Police said Phillips admitted to shooting Estok following a long interview Wednesday afternoon at police headquarters.

He is now facing charges for criminal homicide, along with aggravated assault and aggravated kidnapping for pointing a gun at the girlfriend, threatening to kill her and preventing her from leaving.
