WICHITA, Kan. (AP) — A man charged with fatally shooting another man inside a Wichita restaurant says he doesn’t know why he is locked up.

The Wichita Eagle reports that 20-year-old Jonah Isaac Tausche told a judge Thursday during his first court appearance on a first-degree murder charge that he “ate some meth” and “now I’m here.” Tausche is jailed on $250,000 bond in Monday’s fatal shooting of 47-year-old Tan Van Vu of Wichita at the Bida Saigon restaurant.

But Tausche says there’s “no possible way” when he was told of the charges, which also include possession of cocaine and criminal possession of a weapon by a convicted felon. He described himself as a “peaceful person,” although court records show he has a history of violence going back to when he was 15.
