Earl Melchert said that 15-year-old Jasmine Block and her relatives were more deserving of the cash than him.
As time passed and no one heard from Jasmine, the Alexandria police department chose to help incentivize the community for information regarding her safe return, offering a substantial reward.
Police said that family acquaintance Thomas Barker, 32, had come to the teen's home while she was alone and said he needed help with a family situation.
The girl's mother said she had been waiting to meet Melchert.
The 15-year-old was abducted on August 8 and taken to a home where police said three men sexually assaulted her and held her captive for 29 days, the Twin Cities Pioneer Press reported.
"The reward money means absolutely nothing to me", said Melchert as he addressed Jasmine and her mother, Sarah.
"Thank you Earl, it is people like you that make this world a better place", the chief said.
However, at a gathering at the Alexandria Police Department on Friday, Oct. 6, Melchert turned down the reward and instead gave the money to Jasmine. At that point, she spotted a vehicle belonging to one of the captors driving right past home.
The reward money was offered by the girl's family to anyone who had information on her whereabouts, along with an anonymous donor.
Hamas names mastermind of attacks on Israelis as deputy
While no group immediately claimed Sunday's rocket attempt, Israel holds Hamas responsible for all fire emanating from the Strip. The split has complicated any potential peace negotiations with Israel .
It was that decision that would change the course of numerous lives - especially that of a 15-year-old Jasmine Block.
"Today we witnessed an incredible example of kindness", Alexandria Police Chief Rick Wyffels said on Facebook.
Mr Melchart told local media that "he did what I had to do". "He risked a lot of things and put himself in danger". "It is people like you (who) make this world a better place".
Melchert told The Voice of Alexandria that the experience has made him look at things differently.
All three suspects have been charged with kidnapping, criminal sexual conduct, assault and false imprisonment.
Fox News reported that the girl had been taken to an abandoned house where her captors physically and sexually assaulted her for a month. On Sept. 5, they left her alone while they traveled to a nearby town for lunch.
The three men accused of kidnapping and holding Jasmine are now in police custody, with further investigation pending.
The girl's older sister echoed the sentiment in an interview with the Voice of Alexandria after the presentation of the reward.
"The family needs the money", he told the Times. "I want to present this money to you and Jasmine".
