A man has submitted a detailed dossier to police after dedicating 13 years to investigating the unsolved murders of his stepfather and the stepfather’s girlfriend, who were killed 40 years ago. Ray Price, 66, presented the 82-page report to the Metropolitan Police last week, just ahead of the 40th anniversary of the deaths of Brian Price, 43, and Susan Tetrault, 36, on July 13, 1986. The two were found naked and mutilated in Tetrault’s flat in Clapham, South London, in what authorities believe was a gangland attack.

Brian Price, described as a drug trafficker, had met Dean Alexander, then 25, while in jail. The two were reportedly involved in a plan to import heroin with a Cypriot gangster, a deal that ultimately fell through. Alexander, a convicted bank raider, admitted to being at the flat on the night of the killings but said he left early to visit his girlfriend, though he spent the rest of the night walking the streets after being unable to see her. Despite this, he was acquitted of the murders following a two-week trial at the Old Bailey in 1987.

Ray Price compiled the dossier with help from criminologist Dr. Kirsty Bennett and tracked down Alexander, who has since changed his name and now directs a counter-surveillance firm. Alexander declined to meet with Ray but communicated by text last year, stating he was unaware of Brian Price’s activities or associations and expressed hope that the investigation would lead to the real culprit. He also acknowledged the desire of Ray to seek justice but said he wished to protect his family from revisiting the traumatic events.

Key pieces of evidence from the original investigation included Brian Price’s contacts book, his ring, and £1,000 in cash, all found at his home. The case has remained open but unsolved for four decades. Scotland Yard confirmed officers are reviewing the new information, which was submitted on July 7 by a family member. The force indicated that the case has been under review since first being contacted by a victim’s relative in 2023 and that the material is now undergoing further forensic assessment.

Ray Price expressed hope that the new evidence might encourage authorities to reopen the investigation and bring those responsible to justice, ending a long-standing quest to solve the case.
