The disappearance of 20-year-old Iowa student Mollie Tibbetts vexed her family and authorities for weeks. Mollie was murdered by illegal immigrant Christian Rivera while she was jogging. What we know is that (i) police found Rivera through CCTV which showed a Chevy Malibu connected to him driving around where Mollie was jogging; (ii) Rivera later told police he got out of the car and started jogging alongside Mollie, who threatened to call the cops; (iii) Rivera said he blacked out and when he came he was dragging Mollie’s body out of the trunk. We we did not know is that Mollie was not the only woman Rivera stalked in the town of Brooklyn, Iowa. There were others.
