Trevor described her as seeming "disoriented" during their conversation. She initially told him she was parked outside his house, but upon hanging up and walking out to the street, he did not see her car. When he called her back, she answered, this time telling him she was in her car but was unsure where she was parked. After she told him "I'm fucked up," the phone call ended. This was the last known contact anyone had with her. On October 27, Steppach's 2015 Volkswagen Passat was discovered by a security guard abandoned in a parking lot near a wooded area in Chalamont Park, a neighborhood park in west Little Rock. The security guard notified police and waited approximately 2 hours for an officer to arrive however none did. The next day after seeing the vehicle still there as he did his rounds he once again called and waited for police, who finally arrived around an hour later and discovered it belonged to Steppach. The car had an empty gas tank as well as a dead battery, and the key had been left in the ignition. Several searches of Chalamont Park were undertaken after the discovery of Steppach's car, though no additional evidence was found in the surrounding woods. Per a 2017 report, the men Steppach had accused of sexual assault had all spoken to police, though no formal searches of their cell phones were done for the alleged video of Steppach's rape. In an attempt to bring publicity to her case, Steppach's mother and brother Trevor appeared on "Dr. Phil" in December 2017. The Steppach family offered a reward of $50,000 with information leading to their daughter's discovery. Around 10 a.m. on May 24, 2018, while performing another search of Chalamont Park, police discovered skeletal remains in a drainage pipe in the vicinity where Steppach's car had been discovered. These remains were subsequently confirmed to be those of Steppach. Extensive searches for Steppach at Chalamont Park had been held in the past. Margie Foley, a family friend and mother of one of Steppach's best friends, claimed that she had smelled decomposition while doing a private search of the area, and alerted the authorities. Upon the arrival of police at the scene, Foley claimed she was "kind of dismissed by [the officers]," who told her the park had been searched with recovery canines who would have picked up on the scent of human decomposition, and assured her it "must be an animal or something."
