A state prison inmate will serve at least three more years in prison for repeated stalking of a woman.

Michael Earl Wilson was already serving a sentence for stalking and crimes against the woman when he sent threatening letters last year.

In the mailings, Wilson, 38, writes to the woman: “sleep with both eyes open” and “I am the devil.”

Prior to the start of a scheduled trial this week in Lancaster County Court, Wilson instead pleaded guilty to two felony stalking counts.

In exchange for the plea, Wilson will serve 3 to 6 years in state prison, according to Assistant District Attorney Andrew LeFever.

County Judge Margaret Miller accepted the terms Monday and ordered sentence.

The victim reported the mailings to Columbia police upon receiving them in August 2016. Officer Holly Oster filed charges.

Wilson’s criminal history includes convictions for stalking, aggravated assault, aggravated harassment by a prisoner, burglary, reckless endangerment, and criminal trespass.
