Verified killers

Tom · Daniel Webster

The older account attributes Eric Edwards's 1965 death to his son Tom, who struck him with an axe while Eric was attacking Tom's mother. In the present case Daniel killed Simon Mayfield, Steven Curtis and his mother Lillian Webster; Timothy Webster's confession was false and intended to protect his son.

Verified motive

Tom killed Eric while Eric was violently attacking Tom's mother. Daniel killed Simon and Steven after discovering their affairs with Lillian and believing they were laughing at him, then killed Lillian to end the humiliation and behaviour he could not bear.

Verified important clue

Archive case 29 · checked 16 September 2026The missing victims' mobile-phone records

Simon and Steven arranged secret meetings by text, but their phones vanished; the call records lead back to the affairs with Lillian and disprove Timothy's protective confession because he named the wrong phone.

Verified decisive clue

Archive case 29 · checked 17 September 2026The untraceable phone that disproves Timothy's confession

The victims arranged their meetings by text, but Timothy identifies the wrong handset when he confesses: the dates came from an untraceable phone rather than Lillian's. That mismatch exposes his account as protection for Daniel and redirects the present-day murders to Daniel, while Tom's 1965 killing remains separate.

Verified red herring

Archive case 29 · checked 17 September 2026Timothy Webster's confession to the three present murders

Timothy's jealousy over Lillian's affairs gives the confession an immediate domestic motive and appears to close the deaths of Simon, Steven and Lillian. Phone records and the untraceable messages place the plan elsewhere: Timothy confessed to protect Daniel, whose humiliation and anger drove all three killings.

Verified death and discovery order

Archive case 29 · checked 16 September 2026
