Multiple reports say a witness has claimed that Ray Buck confessed to the killings of Lin Russell, 45, and her six-year-old daughter Megan in 1996. The accounts state that the confession was reportedly made on the same day as the ambush on a country lane in Kent. According to the reports, the claim emerges as investigators consider whether Buck should be treated as a prime suspect in the case.

The reporting also notes that Buck’s son has volunteered to provide a DNA sample, suggesting the case may involve further forensic examination. The articles focus on the witness allegation regarding the timing and content of an alleged confession, alongside the potential for DNA testing to help determine whether any physical evidence can be linked to Buck or other individuals.

As presented in these sources, the key new development is the witness statement describing a same-day confession, rather than new, publicly detailed forensic findings or charges in the summary provided. The reports describe ongoing case developments and steps aimed at clarifying investigative leads.
