Dateline Missing in America – Ep. 25: Marked with an X

It was the early morning hours of May 20, 2017, and 15-year-old Sophie Reeder should have been in bed. Instead, she had slipped out of her house in the River Oaks neighborhood of Fort Lauderdale and walked off into the hot, humid night. Two security cameras recorded some of Sophie’s movements over the next several hours. One recorded her walking past a neighbor’s house as she started her journey; another recorded her walking along a busy road near her home at 2 a.m. In that video, a police cruiser passes the 5-foot-1, 100-pound teenager and doesn’t slow down or stop. Sophie is seen wearing a short black dress, high-top sneakers, a leopard-print fake fur coat, and headphones. They are the last known images of her. Seven weeks after Sophie’s disappearance, police executed a search warrant at an apartment in the area where her phone last pinged. Three convicted felons were staying at that address. Josh Mankiewicz talks with Sophie’s father, Patrick Reeder, her aunt Kirsten Milhorn, reporter Brittany Wallman of the Miami Herald, and Sergeant Don Geiger of the Fort Lauderdale Police Department. The FLPD is offering a reward of up to $25,000 for credible information that leads to the recovery of Sophie Reeder. Anyone with information about Sophie’s disappearance is asked to call the Fort Lauderdale Police Department at 954-828-6677 or email sophietips@flpd.gov.
