WARREN, Pa. — A Warren, Pa., man faces lifetime registration as a sex offender and the prospect of decades in prison as a result of a plea Thursday to charges including rape of a child.

Michael D. Johnson, Canton Street, Warren, entered the plea before Judge Gregory Hammond to two counts of rape of a child and two counts of involuntary deviate sexual intercourse with a child. Each of those charges is a first-degree felony and each carries a maximum of 20 years incarceration.

He was charged back in February. Police were dispatched to Johnson’s residence on Feb. 11 for a report of a male threatening self-harm and spoke with Johnson “who advised,” per the affidavit of probable cause, “that his life had just changed as two female victims were reporting alleged sexual abuse.”

A relative of Johnson confirmed the allegations and police transported Johnson to Warren General Hospital after he “continued to make comments of self-harm.”

Later that day, two females arrived at the city police station to file a complaint.

One victim said she was abused from the age of 6 to 16 and alleged that Johnson forced her to engage in oral sex “weekly” and at “multiple locations in Warren County.”

Police then spoke with the other victim, who reported abuse from the age of 8 to 17. She said Johnson allegedly “made her engage in sexual intercourse” as well as oral sex also weekly and at multiple locations.

That victim told police that Johnson “acknowledged his actions” on a phone call with her grandparents present.

The grandparents confirmed that account.

According to information from the Pennsylvania State Police, all of the offenses to which he pleaded carry a lifetime sexual offender registration requirement under Megan’s Law.

In exchange for the plea, charges that were not prosecuted including two counts of statutory sexual assault, two counts of involuntary deviate sexual intercourse, four counts of indecent assault and other charges.

The case is being prosecuted by the state Attorney General’s office.

Three other pleas were also entered during Thursday’s court proceedings.

Aaron N. Shellhouse, 36, Pittsfield, to DUI. Two counts of failure to stop at red signal were not prosecuted.

Jamie D. Young, 35, Spartansburg, Pa., to simple assault. Charges of strangulation and harassment were not prosecuted.

A not guilty plea was entered by Donna V. Tomassoni, 68, Warren. Tomassoni faces charges of simple assault and harassment.
