Corinna Reid, Robert Cormack guilty in Canary Islands death of son EDINBURGH, Scotland, April 23 (UPI) -- A couple were convicted of manslaughter Tuesday in Edinburgh, Scotland, in the death of their 16-month-old son in 2007 in the Canary Islands. Corinna Reid, 35, and her former partner Robert Cormack, 40, both of Edinburgh, are to be sentenced next month after a jury convicted them of manslaughter but cleared them of homicide in the death of their son Aiden, court records said. The boy's death, which occurred while the family was in the Canary Islands, was originally blamed on bronchitis but Spanish detectives in Tenerife, Canary Islands, asked their Scottish counterparts in 2009 to arrest the couple after toxicology reports showed traces of the heroin substitute methadone and the antidepressant diazepam in the boy's body, the newspaper The Scotsman reported. Documents revealed Cormack, a recovering heroin addict, told Spanish judges his son accidentally drank orange juice mixed with the drugs. The jury unanimously agreed Reid and Cormack had consciously given the drugs to their son but the parents couldn't have known the potentially lethal combination of bronchitis and the drugs, the newspaper said.
