A Pennsylvania man suspected in connection with a terrifying home invasion was tracked down by police using his alleged victim’s AirPods.

Nafis Fisher, 33, was apprehended after a collaborative effort between two police departments led to the identification of the individual who broke into a family’s residence in Upper Southampton early Tuesday morning. A press release from the Bucks County District Attorney’s Office detailed that the man intruded into a house where a mother, a father receiving hospice care, and their 25-year-old daughter were asleep. The daughter reported to the police that she awoke to find a stranger “holding her down on her bed.”

The daughter began yelling, which alerted her mother. Upon facing the intruder, she “momentarily struggled” with him before he escaped, taking various possessions with him.

One of those items was a pair of Apple AirPods.

Officers arrived at the scene at 2:47 a.m. and took note of the missing possessions. During their investigation, the DA mentioned, they recovered a “large kitchen knife” on the daughter’s bed and a 12-foot extension cord, believed by the police to have been brought by the intruder for restraining purposes. At a press conference, Bucks County DA Jennifer Schorn remarked that “it was unmistakably evident that the 25-year-old victim’s room was targeted.”

She continued, “If anyone inadvertently gave information to [the perpetrator] enabling him to select this victim and her family, it is crucial that they disclose that information immediately. It would be far better for them to come forward to us rather than us discovering them.”

Neighbors told police that they saw a black sedan drive away from the family’s home after seeing him run out of the house.

Recognizing that AirPods are traceable through Apple’s Find My app, the authorities used the app to track the AirPods in an effort to locate the suspect. According to the DA, the police monitored the suspect’s journey until the signal halted at a site in Philadelphia.

Officers with the Philadelphia Police Department soon located a black Kia Forte sedan. When an officer with the Upper Southampton Police Department activated the AirPods remotely, it emitted a signal that came from the direction of the car. Sleeping inside the car was Fisher, along with the allegedly stolen items from the family’s home.

Fisher was arrested and charged with several felonies including burglary, aggravated assault, robbery, criminal trespassing, theft by unlawful taking, receiving stolen property, and simple assault. He was booked into the Bucks County Correctional Facility on $250,000 bail.
