INDIANAPOLIS - A wooden cross memorial with the words "proud father, husband, son and friend" stands on E 16th Street near N Post Road where a 40-year-old man named Jeremy Davis was killed in a hit-and-run crash while riding his motorcycle last month. Now, police believe they know who's responsible – they just need to track him down. Around 8:20 on a foggy mid-December night, a woman named Lindsey tells us she heard a loud "boom" outside her house. She ran out to find a motorcycle in pieces and a man barely breathing. "It was just really sad," she said. "I wanted to help him, but there wasn't anything I could do. It was just sad. I hoped he would've made it." Lindsey says she called 911 and held his hand until the ambulance got there – but whoever hit Davis had already taken off. "I found out on Life360 that my husband was at the morgue," said Amanda Davis, Jeremy's wife. "It made me panic, so I called and they told me that my husband was in an accident." Amanda has spent the last month wondering why the other driver didn't stop to help her husband. "Ten days before Christmas, I had to explain to my kids that their dad was gone," she said. “It’s been really hard, the holidays especially. I got my son a Lego set and he was really sad because he was used to doing those with his dad.” Jeremy Davis was one of 28 people killed in hit-and-run crashes in Indianapolis in 2024 alone, the highest number of victims in the last five years. According to IMPD, 16 people were killed in hit-and-run crashes in 2023. The years 2022 and 2021 each saw a total of 22. In 2020, there were 17 hit-and-run fatalities.

The probable cause affidavit describes how police at the scene that day learned of another hit-and-run that damaged a woman's car and happened within minutes just down the street. Using witnesses, surveillance footage, cell phone information, ALPR data and evidence from the scene, detectives traced both crashes back to the same work van from a plumbing company that they believe was driven by an employee named Caiden McCall. "For it to happen once is horrible but twice, I just don't understand," Amanda Davis said. "To know that they’re out there, free, it’s just a horrible feeling. I still have nightmares." Court documents said a witness told police the van was in the wrong lane when it collided with Davis. In an interview with detectives, McCall reportedly changed his story about what happened several times and "began shaking uncontrollably." Since then, an arrest warrant has been issued on the following charges: leaving the scene of an accident resulting in death or catastrophic injury and leaving the scene of an accident where the driver fails to immediately stop at the scene. "I guess it's kind of bittersweet to have a name but not know who it is or where he's at," Amanda Davis added. "It’s not going to bring him back, of course, but it’ll give me peace that he’s not out being careless and hurting someone else." She and other loved ones say they hope to find closure in justice being served, although it wouldn't bring Jeremy back--a father of six, a grandfather and an army veteran who served two tours in Iraq. "At least he went doing something that he loved, but it doesn't make it a lot easier," she said. "I miss him so, so much." Jeremy's sister-in-law, Gabrielle Thomas Simpson, added, "I just beg you to turn yourself in, please. This man had a family that really loved him, children that adored him, grandchildren. Just turn yourself in." "I think people aren’t respectful to human life anymore," Lindsey said. "One time could be an accident. After that, you left the scene, it’s not an accident. You need to be punished. You took someone’s life.”  IMPD declined FOX59/CBS4's request for an interview Tuesday, saying this is still an active and ongoing investigation. FOX59/CBS4 reached out to the plumbing company that owns the van mentioned in court documents, but at the time of this article's publication, has yet to hear back.
