Grieving mother believes 'third party' was involved in son's death

The heartbroken mother of a Scottish teenager, who was missing for a month, believes a 'third party' was involved in her son's death.

Nineteen-year-old Cole Cooper vanished on May 9, sparking a four-week major search which involved helicopters, divers and specialist teams to track him down.

He was last spotted on CCTV five days before, trying to enter his father's home after a house party.

After assessing 2,000 hours of CCTV footage and speaking to over 400 people, Police Scotland found the young man dead in a wooded area near Falkrik.

Now his grieving mother Wendy Stewart, 42, believes there was 'third party' involvement in her son's death.
