The grieving mother of a British woman shot dead by her own father in Texas has arrived at the offices of US prosecutors to demand a fresh investigation into her daughter’s death.
Jane Coates, 49, travelled more than 4,000 miles to the Collin County District Attorney’s Office, where she called for the probe into the shooting of her daughter Lucy Harrison to be reopened.
She said: ‘I’ve come all this way because I wanted to look these people in the eye and ask them some very simple questions about my daughter.
‘I’ve travelled thousands of miles to Texas because I’m not prepared to give up on Lucy. I never will.’
Ms Harrison, 23, a fashion buyer from Warrington, Cheshire, was shot in the chest on January 10, 2025, by her father Kris Harrison while she was visiting his home in Prosper, an affluent town north of Dallas.
Although local police launched an investigation, records show the shooting was treated as an accident from the outset and Mr Harrison, 52, was never arrested.
Mr Harrison claimed that his gun had accidentally gone off in the master bedroom of his detached home as he showed it to his daughter minutes before she was due to leave to travel back to the UK.

A Texas grand jury found there was no case to answer, but a UK coroner concluded at an inquest earlier this year that Ms Harrison had been unlawfully killed.
Ms Coates says the investigation into her daughter’s death should be reopened, arguing key lines of inquiry were never properly explored.
Standing outside the district attorney’s office today, she called for officials to meet with her and hear her concerns.
‘I just wish they cared enough to meet me… I have lost my daughter. I can never get her back,’ she said.
‘The very least I thought I could expect was for the people responsible for investigating her death to give me the courtesy of sitting down with me and hearing me out.’
Ms Coates has pointed to several gaps in the initial investigation, including the failure to carry out toxicology tests despite officers smelling alcohol on Mr Harrison at the time of the shooting.
She also highlighted the lack of gunshot residue testing, inconsistencies in Mr Harrison’s account and questions surrounding the bullet trajectory and entry wound.
‘These are not minor errors or omissions. They are fundamental to any homicide investigation and they simply weren’t done,’ she said.
Her concerns have been echoed by Craig Miller, a respected former Dallas police chief who reviewed the case files and found investigators did not appear to follow several key lines of inquiry.

Mr Miller, who now works as a law enforcement expert witness, agreed there were several departures from what he described as nationally accepted investigative ‘best practice’.
Welcoming his findings, Ms Coates said: ‘We have been saying for a long time that Lucy’s death was not properly investigated.
‘Craig Miller’s review is so important… he is a former senior Dallas police officer who understands the standards expected of a major American police investigation.’
Ms Coates’s visit to Texas comes after repeated requests for meetings with both Prosper Police and the Collin County District Attorney’s Office were declined, according to the campaign for justice for her daughter.
Appealing directly to the authorities, Ms Coates urged them to reconsider, adding: ‘Lucy deserved a proper investigation when she died. She must have one now.’
Radd Seiger, spokesman for the Justice for Lucy Harrison campaign, said Mis Coates had been forced to make the journey because she still had not received answers after her daughter’s death.
‘We decided to come to Texas to appeal directly to the American people about the gross injustice in Lucy’s case,’ he added.
‘Having been here for a couple of days now, we have been quite simply overwhelmed by messages of support from people in Prosper, Collin County and right across Texas.
‘You do not need to be a lawyer or police officer to spot the terrible gaps in the investigation.
‘There is no other way to put it, I am afraid. The Texas authorities let Lucy down. They have let her loved ones down.’
He added: ‘Lucy and her loved ones deserve justice. The police and District Attorney responsible for this mess can run from the truth, but they cannot hide from the people.’
The campaign plans a week of media appearances and public engagements in Dallas as pressure grows on local authorities to revisit the case.
Prosper Police and the Collin County District Attorney’s Office have maintained that the investigation into Ms Harrison’s death was ‘thorough and complete’.
A fundraising campaign to help cover the family’s travel costs has so far raised more than £7,000.
