HOUSTON The man who taped an interview for the Dr. Phil show days before police say he confessed to killing his ex-girlfriend in Houston and then dumping her body hundreds of miles away in a West Texas oil field told the TV personality he didn t murder the woman.

Mark Augustin Castellano has been charged with murder in last month s slaying of 31-year-old Michelle Warner.

Police say Castellano confessed on Sunday, two days after taping an interview with Dr. Phil host Phil McGraw.

In a clip released by the show Tuesday, McGraw asks Did you kill her?

Castellano replies, No sir.

Castellano also denied hiding Warner s body. The interview will air Thursday.

Police say Castellano drove Warner s body from Houston to West Texas before burying it in a ditch near Midland.
