Haffa became trapped under the vehicle and fire crews had to use both air bags and emergency jacks to remove him. Lynn Taborsak, a longtime volunteer with the city’s homeless, said Haffa had spent the past three winters sleeping at the overflow shelter operated by the First Congregational Church. Police said Kim Siladi, 61, was driving the SUV eastbound on Madison Avenue, turning right on North Street, and did not see the bicyclist, who was riding his bike northbound on North Street.
