Kimberley Bray, 46, of Newall Green was convicted of possession of some of the weapons, the Manchester Evening News reported. Bray said she did not know Paul Taylor, 46, kept a large stash of weapons in their house but witnesses testified police who raided their home found some guns hidden under a duvet, suggesting they had been hastily concealed.
Taylor, who investigators said allowed criminal gangs in the Manchester area to keep their weapons in his house, received a 17-year sentence. One weapon, a 9 mm handgun believed to have been smuggled into Britain from Iraq, has been linked to at least three shootings, police said.
A defense lawyer said Taylor was forced into hiding the weapons because he owed money for illegal drugs.
Bray worked at St. Paul's Catholic High School in Wythenshawe.
