A man Washington County authorities say tried to kill his former girlfriend is in custody.

As WTAP-TV and WTAP.com first reported, 19-year-old Thaddeus Salomon allegedly stabbed 23-year-old Susan Lawson early Tuesday morning outside her home in New Matamoras.

Washington County Sheriff Larry Mincks says Salomon was arrested near the Pleasants-Tyler County line Tuesday afternoon.

Daisy Goodman, the mother of Lawson, tells WTAP-TV Salomon was staying at her house because "he had no place to go."

Lawson was stabbed in the lower back. She was transported by helicopter to Grant Medical Center in Columbus with what were called "life-threatening injuries."

Salomon faces attempted murder charges. He is behind bars in Pleasants County awaiting extradition.
