Inquest Rules Barnsley Couple Died From Combined Heroin, Cocaine and Methadone Toxicity

Forensic toxicology underpinned the ruling alongside testimony about long‑term drug dependence.

Overview

  • Claire White, 32, and Mark Martin Sinton, 42, were found unresponsive at their Priory Road home by Sinton’s mother on February 21.
  • Inquest evidence said the pair returned home around 5pm on February 20 and went straight upstairs without speaking to the household.
  • Police documented a positive pregnancy test along with a crack pipe and other drug paraphernalia at the scene.
  • Post-mortems and toxicology led the coroner to record drug-related deaths caused by the combined toxic effect of heroin, cocaine and methadone.
  • The coroner said it was impossible to determine which partner died first.
