As RadarOnline.com has learned, the 20-year-old student's reward has now hit $260,000, less three weeks after her disappearance.
Apart from the money that family and friends have provided, strangers from across the country have donated to Tibbetts' fund, in hopes that her abductor will take the money and bring the student back, safely.
In an interview with Fox News, Tibbetts' father, Rob, said that he believes his daughter is still alive and has been kidnapped by someone she knows.
"It's totally speculation on my part, but I think Mollie is with someone that she knows, that is in over their head," he said. "My two cents is that no one went into that house to hurt her."
Radar previously reported that Tibbetts went missing on July 18 after going jogging at around 10:00p.m. around her boyfriend's home in Brooklyn, Iowa.
Her entire family has been cooperating with authorities and talking to reporters since the incident, with her father even saying he believes the kidnapper doesn't know how to get out of the situation, which is why he/she hasn't brought Tibbetts back.
Investigators are still conducting interviews regarding Mollie Tibbetts' disappearance and will continue searching for any clues leading to her body.
