This terrifying cache of high-power weapons was allegedly found inside a secret basement bunker in the home of two school bus drivers. Steve and Sarah Nick built up the huge arsenal, including a 50-caliber machine gun, a sniper rifle, and 17,000 rounds of ammunition, after it was claimed they stole more than $50,000. Many of the 30 weapons were legally owned, but the couple, who are said to have links to the Michigan militia, are accused of plundering Mrs Nick's 67-year-old mother's savings to fund the potentially deadly haul.

Police raided their home in Davison Township, Michigan, after concerns were raised by adult protective services in August last year. It is alleged that the husband and wife had gained access to Mrs Nick's severely ill mother's bank account and were writing blank bank cheques to themselves. As well as the huge weapons haul in the basement bunker, officers also discovered a number of bullet proof vests, including one for the couple's nine-year-old daughter. One of the vest had a patch on it that read, 'We kill for peace,' the website reported. Mrs Nick. 32, was employed as a bus driver for the Flint School District and her 33-year-old husband was said to work for Davison Schools. Genesee County Sheriff Robert Pickell said that his officers had seized all of the weapons. 'It's an issue because they were purchased with stolen money,' Pickell reportedly told mlive.com .
