Finding a Runaway Teen Through TikTok Duet Geolocation

Background

A family reported their 15-year-old missing after the teen left a note saying they were "leaving for good." The teen's phone was turned off, but their TikTok account remained active.

Investigation Methodology

1. TikTok Activity Monitoring: We tracked the teen's TikTok account for new posts, likes, comments, and duets in real-time.
2. Duet Geolocation: Two TikTok duets posted by the teen contained background audio and visual clues that were analyzed for location markers.
3. Network Analysis: The teen's recent TikTok followers and following changes were analyzed to identify potential contacts who may have facilitated the departure.

Key Findings

• A duet video posted 14 hours after disappearance contained ambient audio from a specific radio station broadcasting in a city 300 miles away.
• Background details in the video (a distinctive mural and street sign) were matched through Google Street View to a specific neighborhood.
• A newly followed TikTok account belonged to a 19-year-old in that same city, confirmed through their own publicly geotagged content.

Outcome

Location intelligence was provided to law enforcement within 22 hours of engagement. The teen was located safe. This case was pro bono.
