It's been a nightmare for years. Investigators say 15-year-old Sophie Reeder disappeared without a trace from her Ft. Lauderdale, FL home on May 20, 2017. At the time, she was only 15-years-old.

When Patrick Reeder noticed his daughter was missing, he thought maybe she went to visit a friend. Patrick said he saw his daughter the night before and when he walked into her room, all he found was a candle burning.

It wasn't until Patrick made a series of calls when he figured out his daughter may be in trouble and he needed to file a missing persons report with police.

Only one week before Reeder vanished, she spent time with her mom Nicole Easely-Twist on Mother's Day. The National Center for Missing and Exploited Children said, "The pair went out to eat, to the local mall for some shopping, and afterward Nicole dropped Sophie off back at her dad’s house."

Ft. Lauderdale police said Sophie was last seen on surveillance video walking down West Davie Boulevard away from her home. Reeder is seen in footage wearing headphones, doesn't appear to be walking with anyone, her hair is in buns and she is wearing white headphones. In the short clip Sophie is wearing a larger jacket and shorts.

Reeder stands 5 feet 1 inches tall and when she went missing, she weighed 120 pounds. It's possible she could be wearing a wig. In an interview with NCMEC, Twist said her daughter loved to listen to music,“She would go from listening to Nirvana to Tupac. The last one she was really into was Lana Del Rey.”

The National Center for Missing and Exploited Children created the age enhanced photo above of what Reeder may look like today. If you know anything, please reach out to the "In Pursuit" hotline directly. Remember, you can always remain anonymous: 833-378-7783
