Simon Peter Carman, a 45-year-old British-born Australian handyman, has been charged with murdering 17-year-old Tunchanok Donhomla, whose body was found in a suitcase near railway tracks in Pattaya, Thailand. Carman allegedly met the teenager on Beach Road, brought her to his condominium, and later attempted to flee to Perth before being arrested at Bangkok's airport. He claims self-defense after a dispute over payment of 1,000 baht ($43.45), while CCTV footage allegedly shows him wheeling the suitcase away. The victim's parents demand execution, and Carman faces charges including murder and offenses relating to a minor, which can carry the death penalty in Thailand.
