Dallas, DeSoto and Grand Prairie police searching for missing 25-year-old woman, authorities say

DeSoto, Dallas and Grand Prairie police are conducting a large-scale search and rescue mission for a woman who has been missing since early Sunday.

Yi Chan, 25, was last seen by her family between midnight and 1 a.m. in the 500 block of Olympia Street in DeSoto. Her family told police that she left home in a “depressed state” and that they feared for her safety.

Dallas police found Chan’s car with the keys inside on Mountain Creek Parkway on Sunday morning. After hearing the family’s concerns about her mental health, the three departments launched a land, air and water search, police said.

DeSoto police dispatched members of the criminal investigation division, the UAS (Drone) Team and regional drone operators, and multiple K-9 units with the Search One Rescue team to patrol the shoreline. Investigators are working to establish a timeline of Chan’s whereabouts, police said.

Boats from Dallas Fire-Rescue and the Grand Prairie Police Department’s lake operations are being used, police said.
