Mexican authorities said Sunday they have detained a 59-year-old American man over the death of his girlfriend at a resort in Playa del Carmen. The victim, Missouri native Tamra Turpin, 36, was found dead Wednesday in a condo the couple had rented, according to the St. Louis Post-Dispatch. She died of asphyxia by strangulation, according to a forensic report. Authorities said the man, identified as John Loveless, was arrested at the Cancun airport before attempting to board a flight to Atlanta. Family members told the Post-Dispatch that the boyfriend said she had been taken to a hospital with seizures. He reportedly told them she was released but “still wasn’t right,” and that she died at the hotel Wednesday morning.
