Christina and Lucy were shot by a .410 caliber double-barreled shotgun, but Banner says he never should have had it. One year before the murders, Lowe had threatened to shoot Banner and she reported him to the police.
"He said he was going to blow my head off, so I ran - and I ran for my life," Banner says.
Police seized Lowe’s guns, but returned them four months before Christine and Lucy's murders. Banner says there was never a proper investigation or good reason to give Lowe his guns back.
“The police should never have given an 82-year-old man seven shotguns back," she says. "Why wasn't he mentally health checked? Why didn't they do their job?”
The IPCC (Independent Police Complaints Commission) conducted a report on the return of Lowe’s guns, and found there was “gross misconduct.”
A police spokeswoman said, “In 2014, the force commissioned two independent reports from Hampshire Constabulary and North Yorkshire Police which indicated the decision by firearms licensing officers to return weapons to John Lowe was flawed and did not meet national standards.Whilst the full investigation into this matter remains on-going, in light of these early findings we have spoken with members of Christine and Lucy Lee's family to apologize for this."
The staff in charge of returning Lowe's guns were ultimately dismissed.
A spokesperson for Stacey Banner said: "The IPCC recommendations in this shocking case include that the licensing team should liaise with officers investigating allegations against firearms license holders. In other words, the IPCC is recommending that licensing team staff do their job. It is a vindication for Stacy Banner that staff faced dismissal proceedings and one was sacked, and that both local and national recommendations have been made."
"It is devastating to see your worst fears confirmed in black and white about how those entrusted with the public safety can abuse and neglect their powers," Banner says. "But for the police's failings, my mum and sister would be here today."
