Madore, who was arrested in Strafford on assault and reckless conduct charges, was later involuntarily admitted at New Hampshire Hospital in Concord, according to records.
Madore was fatally shot by a state trooper shortly afterward.
The guns used in 2016 remain in the custody of the Strafford Police Department, he said.
It remains unclear how Madore, who had most recently lived in a hotel in New Hampshire's Seacoast area, acquired the guns found Nov. 17.
A celebration of life has been scheduled on Nov. 27 for for Haas, 63, a former police chief from Franklin, New Hampshire.
