A western Kentucky sheriff says a teenage boy has been killed and his mother abducted by an ex-boyfriend and found dead in Ohio.

Graves County Sheriff Dewayne Redmon says 41-year-old Terry Froman of Brookport, Illinois, was taken into custody Friday after Ohio authorities stopped his vehicle and found the woman dead inside. Redmon says murder and kidnapping charges have been filed against Froman.

The sheriff says 17-year-old Michael Mahoney's body was found by authorities in his home Friday morning in Mayfield, Kentucky.

Redmon says 34-year-old Kim Thomas' abduction led to a multi-state search.

He says the bloodied Thomas tried to flee at a food mart in Paducah, Kentucky, on Friday morning, but Froman caught her, put her in the vehicle and took off. Authorities stopped the vehicle in the Cincinnati area.
