A man charged in the killings of a Wisconsin woman and two girls more than a week ago was arrested Thursday, authorities said.

Virgil Thew was arrested about 30 minutes after someone reported a suspicious person in Elroy, a small community about 12 miles from New Lisbon, where the killings occurred, the Juneau County Sheriff’s Office and New Lisbon police said.

No further details were released.

Elizabeth Kolba, 33, and two girls, ages 12 and 13, were found shot to death in a New Lisbon home on Dec. 30. The suspect knew the victims, according to a criminal complaint.

In the following days, the New Lisbon Police Department officially opened a murder investigation, and by Jan. 6, the FBI and U.S. Marshals had joined the search, CBS affiliate WKBT reported.

Thew, 47, is charged with three counts of first-degree intentional homicide, online court records show.

It was not immediately known whether he already had an attorney who could respond to the allegations. None were listed in court records, and New Lisbon police declined to further discuss the case.

Law enforcement in the area has been searching for Thew since the murders and posted his name and photo on social media.

“We appreciate the public’s assistance in providing tips that helped resolve this matter successfully,” police said.
