Felicia West lives in a trailer park in Matteson. Police say they went to her home last Thursday on a domestic dispute call and found fireworks and black powder in the home.
Her 5-year-old daughter was also inside.
The bomb squad was called in. Items seized include 300 pounds of fireworks, 51-pounds of flash powder and 3300 m-type explosives.
Police are now looking for a 'person of interest' in the case.
