5:30 p.m.

A woman who walks her dog in the woods just south of the Swiss city of Schaffhausen says she has seen the suspect in Monday’s chainsaw attack several times in the last few weeks.

Therese Karrer, who lives in the small village of Uhwiesen, said Monday: “I talked to him a few times and walked by his car every day with our dog.”

Karrer said suspect Franz Wrousis showed up three or four weeks ago in the forest. He chatted with her once when he was having breakfast. She says “he may have been a little strange, but he wasn’t unfriendly — I never felt threatened.”

Swiss police, who are still hunting for Wrousis, described him as aggressive and unstable. They say he wounded five people in a Swiss insurance office Monday in Schaffhausen.
