A Kyle man who authorities say held a knife to the neck and stomach of his 2-month-old son during an argument with his girlfriend has been sentenced to a year and a month in prison.

Thirty-three-year-old Matthew Iron Sr. was convicted of felony child abuse and neglect in the November 2016 incident on the Pine Ridge Indian Reservation in which authorities say he threatened to kill the child. He surrendered after a 45-minute standoff with police.

Iron was sentenced Monday. U.S. Attorney Ron Parsons says he'll be on supervised release for three years following his time behind bars.
