The 24-year-old man who was charged with killing 20-year-old Brooklyn, Iowa college student Mollie Tibbetts allegedly had a history with following girls in his car.
Cristhian Rivera was arrested earlier this week after police saw him talking to Tibbetts on a neighbor's surveillance video the night she disappeared. He told detectives he approached her during her run, and when she told him to leave her alone and that she would call the police, he "blacked out."
When he came to, Rivera said he was in his car with headphones in his lap and knew that her body was in the trunk. He carried her to a nearby cornfield, where her body was later found. She died from "multiple sharp force injuries."
And it seems like this isn't the first time Rivera has approached a woman in his car. Bailey Gibson, 18, said he once "creeped out" her younger, 17-year-old sister.
Gibson, who is also a resident of Brooklyn Iowa, said that at first, her sister thought Rivera was nice.
"I know Cristhian from my sister. She thought he was a nice, well-spoken person. They hung out a few times but nothing really happened romantically," Gibson said.
She started feeling uncomfortable around Rivera after he approached her in a manner similar to how he approached Tibbetts.
"She told me that a little while ago he drove up to her while she was walking through Brooklyn," Gibson said. "He told her she was really pretty and things like that. It was more flirty than sexual but my sister is very shy. She didn’t appreciate it."
"Even though she knew him a little she felt unsafe and didn't want to talk to him. In the end, she was really creeped out by his behavior. She had to keep telling him she wasn't interested."
Thankfully, Rivera left Gibson's sister alone. They didn't think anything more of the interaction until they learned about Tibbetts' murder.
"It all clicked when we heard the news. It's so scary to think he did something similar with my sister," she said.

Another man — who was only identified as Justin — claimed that Rivera followed his fiancée in his car.
“I remember her calling me when she noticed how slow he was driving by in circles, turning around the block to keep up with her several times on her walk home,” he said. “I vividly remember one day, it was around sunset or just after, my fiancée called because she was scared."
Justin said she was returning from getting groceries when Rivera drove past her at least six times.
"Now it’s really strange because of how long he’s been driving around like that. It makes you wonder if Mollie was his only victim.”
In his first court hearing, Rivera didn't enter a plea, and his cash-only bond was set to $5 million. His next hearing will be on Aug. 31.
