A 24-year-old German man managed to cut off his own head with an electric chainsaw after he stabbed his father in their Cologne apartment. The 70-year-old man was found near death when police arrived.
Senior prosecutor Alf Willwacher said, "We do not believe any third party was involved." According to neighbors, the pair went into seclusion several years ago after their mother allegedly committed suicide.
