Jane Coates traveled from England to North Texas seeking answers about her daughter’s fatal shooting, but left visits to the Collin County District Attorney’s Office and Prosper Police Department without a meeting with their senior officials.

Coates visited the offices Monday, Sept. 28, as part of her campaign for a fresh investigation into the January 2025 death of 23-year-old Lucy Harrison. According to FOX 4’s account of the visits, staff said District Attorney Greg Willis and First Assistant District Attorney Bill Wirskye were unavailable.

Coates and her adviser, Radd Seiger, did speak with a DA investigator, whom they described as empathetic and respectful, NBC 5 DFW reported. Prosper police declined to meet with them.

Harrison was shot at her father Kris Harrison’s Prosper home on Jan. 10, 2025, while visiting family from England. Her father told investigators the shooting was accidental and occurred while he was showing her his handgun.

The DA’s office said Prosper police investigated with assistance from the Texas Rangers, and neither agency found probable cause for an arrest. A Collin County grand jury considered the case in June 2025 and declined to indict Harrison for criminally negligent homicide.

A subsequent UK inquest reached a different conclusion. In February 2026, Cheshire Senior Coroner Jacqueline Devonish found that Lucy Harrison had been unlawfully killed on the grounds of gross negligence manslaughter, according to the BBC’s reporting on the inquest.

An inquest establishes the circumstances of a death; it does not determine criminal liability, according to the UK government’s guidance. The finding was not a criminal conviction.

Coates has questioned whether Texas investigators sufficiently examined the shooting. In its September investigation report, FOX 4 said police records documented alcohol on Kris Harrison’s breath and his admission that he had consumed wine. The records did not document a breathalyzer or blood test, or show evidence of a crime scene reconstruction.

Prosper police said the investigation was thorough and complete. Citing the completed investigative and prosecutorial processes and legal considerations, the department said it would neither reopen the case nor meet with Coates.

An attorney for the town cited threatened civil litigation as a reason for declining a meeting. Coates disputed that explanation, telling FOX 4 no civil litigation had been suggested.

Coates and Lucy’s boyfriend, Sam Littler, have submitted complaints about the investigation. Through her “For Luce” campaign, Coates continues to seek reconsideration of the case.
