A 21-year-old Minneapolis man was killed in the Nov. 3 incident.
Each of the 14 suspects carries a $5,000 reward.
More than 30 reports of car windows being shot out by BB guns were received.
The woman was walking home during the day when she was attacked.
'You guys deserve this,' he told the 15-year-old and her family.
The agency hopes the reward will encourage more people to come forward.
CAIR-MN is offering $10K for information leading to an arrest.
