Police are now offering a reward of as much as $10,000 for tips on who opened fire at a New Year's Eve party in Maryland, seriously injuring two people.
A stray bullet hit Marshall University football player Larry Aaron III in the back, paralyzing him, according to news reports.
Anne Arundel County police announced the reward on Thursday and pleaded with partygoers to come forward.
"The police department is asking that anyone with recordings, photographs or information, no matter how insignificant you think they may be, to please contact Detective Pattana of the Anne Arundel County Police Department," a notice says.
Police believe that more than 100 people were at the party on the 7800 block of Bastille Road in Severn where someone opened fire. Police responded about 1 a.m and rushed Aaron to a hospital.
Aaron was shielding his girlfriend when he was shot, his father, Larry Aaron Jr., told WBAL-TV.
"I know they say you're not supposed to ask why, but you know, my son had everything going for him," his father, Larry Aaron Jr., told the station. The 19-year-old is now paralyzed from the waist down.

Doctors cannot operate on Aaron because the bullet is lodged in his spinal cord, his mother, Melissa Aaron, told WBAL-TV. He is struggling to cope with his life-changing injury, she said.
"He has his moments. He's been very calm, but he has had a few breakdowns, and that's to be expected," she said.
John "Doc" Holliday, the head football coach of Marshall University, sent his condolences to Aaron and his family.
"It is however with a heavy heart that we bring in this new year as I send my thoughts and prayers to Larry Aaron and his entire family during this difficult time. Your @HerdFB family is here for you. #HerdStrong," he wrote, referring to the Marshall Thundering Herd.
Officials at Marshall University, which is located in Huntington, West Virginia, did not respond to inquiries.
Police said earlier this week that a 17-year-old boy also was hurt. In an update Thursday, they called his injury "serious." Additional information was not available immediately.
