Two Waterville women have been charged with aggravated attempted murder in the stabbing this month of a woman in China.

Maine State Police on Thursday charged Carissa Butkewicz, 23, and Tiffany Glidden, 20, with stabbing Kathryn Hopkins, 24, in the stomach Nov. 4 with a kitchen knife as Hopkins sat in her car on Fire Road 17, off Neck Road, said Stephen McCausland, spokesman for the Maine Department of Public Safety, in a news release Friday.

A police affidavit filed in Kennebec County court says Glidden confessed to a detective that she and Butkewicz planned the stabbing.

McCausland said in the release that “the two women had earlier texted Hopkins to meet them there.”

According to the affidavit, when Hopkins arrived at Fire Road 17, Butkewicz sat in the passenger seat of Hopkins’ vehicle while Glidden watched from behind a tree, holding a bat, Glidden told police.

After a few minutes, Glidden heard Hopkins scream “Carissa” loudly and Butkewicz got out of Hopkins’ vehicle, Glidden told police. Hopkins then began to back out onto Neck Road.

“Tiffany said she ran out from behind the tree and began to smash the windshield of Kathryn’s vehicle as she was attempting to leave,” the affidavit says. “Tiffany asked Carissa where the knife was and Carissa replied that was in her stomach.”

At that point, Butkewicz and Glidden ran to a home to ask a woman who had earlier driven Glidden and Butkewicz from Waterville to China to take them back to Waterville.

That woman, Karen Willette, told police that Butkewicz told her, “I just hurt someone really … bad,” according to the affidavit.

McCausland said Hopkins, “drove a short distance and received medical attention for her stab wound from a nearby resident until an ambulance arrived.”

He said that “her condition has improved since the incident.”

After the stabbing, police sought Butkewicz and Glidden for questioning and both turned themselves in last week. They were held on unrelated charges until Thursday’s new charges.

Both women were due to appear in court Friday.
