Detectives Search for Missing Woman in Maryland  

Franconia Police District – Yesterday, detectives searched the area near Piscataway Park in Maryland for a 35-year-old woman reported missing on Sunday, March 6. Hannah Choi was last seen on Saturday, March 5 at her home in the 5300 block of Jesmond Street in the Alexandria section of Fairfax County. Friends arrived at Ms. Choi’s home on Sunday, but Ms. Choi did not answer the door. Ms. Choi missed several appointments and could not be reached. Her friends contacted police out of concern for her wellbeing. Our officers searched the home, and the house appeared to be in order except for bedding which appeared to be missing from a bedroom. Based on her sudden disappearance, detectives from our Major Crimes Bureau assumed the investigation.  

Through interviews with friends and family, detectives discovered Ms. Choi spent significant time on Saturday, March 5 with her live-in ex-boyfriend, Joel Mosso Merino, 27, of Alexandria. Detectives believe during their time together Ms. Choi may have sustained a significant injury. Detectives believe Merino then removed Ms. Choi from the home and transported her to another location.  

Detectives identified a vehicle they believed Merino was operating the night of Ms. Choi’s disappearance. The vehicle was located the following day, March 7, in Washington, D.C. A search warrant was executed on the vehicle, and although Ms. Choi was not found, detectives discovered evidence to suggest Ms. Choi was harmed prior to her disappearance. Based on the evidence recovered from the vehicle and additional interviews, detectives obtained a warrant for Merino for second degree murder and the disposal of a body. 

Joel Mosso Merino

Detectives from our Fugitive Track and Apprehension Unit immediately assumed the investigation and began tracking Merino’s whereabouts. They quickly determined Merino fled the state and notified the United States Marshals Service to aid in apprehending Merino. 

Detectives from our Homicide Squad continue to investigate the circumstances surrounding Ms. Choi’s disappearance. Based on records returned from search warrants, they identified Merino spent a significant time in a park in Prince George’s County the night of Ms. Choi’s disappearance. Officers from our Search and Rescue along with our partners from the Fairfax County Fire and Rescue Department, George Mason University Police Department, U.S. Park Police and Mason-Dixon Search Dogs searched the area near Piscataway Park for two days. Detectives continue to review evidence to potentially identify additional locations to search.
