DENVER - SEPTEMBER 13: A Colt AR-15, now legal with a bayonet mount, flash suppressor, collapsible stock and a high capacity magazine that holds more than 30 rounds, sits on the counter of Dave's Guns September 13, 2004 in Denver, Colorado. Between 1994 and September 13, 2004 these guns could only be sold to law enforcement and military but now it is legal for civilians to purchase them due to the expiration of the Brady Bill.

CARSON CITY, Nev. (AP) — Authorities say a couple kept a cache of weapons and lived with their two small children at a northern Nevada children’s museum. KRNV-TV in Reno reported Friday a 41-year-old janitor at the Children’s Museum of Northern Nevada was arrested late last week. He has been charged with child neglect and weapons-related offenses. The Carson City Sheriff’s Office says officials realized the family was living in the museum after the man’s 2-year-old child was discovered walking nearby unsupervised. Another sibling then gave the museum as their address. The children’s mother was a museum manager and both parents have been fired. The museum’s board issued an apology and has closed temporarily while they find a new manager.
