Police are investigating a mass stabbing where a 42-year-old man entered the Walmart in Traverse City and used a folding knife to stab 11 people.

TRAVERSE CITY, Mich. − Authorities on July 27 were still trying to determine why a 42-year-old man went on a stabbing rampage at a local Walmart, wounding 11 people and prompting chaos as patrons scrambled to exit the building.

Eleven people were stabbed at a Walmart in Traverse City on Saturday — with six in critical condition — in what a Michigan sheriff said appeared to be a random act. A suspect was in custody, authorities said.

A 64-year-old Traverse City woman is in the hospital for non-life-threatening injuries after a reported stabbing at a Garfield Township apartment complex Tuesday evening, according to the Grand Traverse County Sheriff's Office. The sheriff’s office said it does not believe there are any safety concerns for the rest of the community.

"When she broke free, he indicated he was still looking for her, and would have kept going if he found her," court documents said.
