The events that led to Mendoza’s arrest started with a person driving down the road and seeing the girl outside a black Chevy with a man near her and pleading for help. The driver accepted the girl into his car and took her to the fire station right away for help.

Once there, police say Mendoza followed and drove the black Chevy right into the car that was parked outside the station, causing a collision. He then yanked the girl out of the car and hurt her badly. The Larimer County Sheriff’s Office described it as a violent physical assault. After that, the sheriff’s office said “the Good Samaritan intervened and restrained the suspect” until a law enforcement officer arrived.
