After he shot himself, the Kansas man was able to walk to the site of a traffic accident to ask law enforcement for help.

Sedgwick County Sheriff's Lieutenant Tim Myers says the man is in critical condition after the accident Wednesday morning in Derby, 10 miles south of Wichita.

The Wichita Eagle reports that Tim said his deputies and a Derby police officer that he was renovating a house when he slipped off a ladder with the nail gun in his hands.

When he landed, the nail gun hit him in the back of the head and the man ''inadvertently pulled the trigger with his finger.''
