ANCHORAGE, Alaska (AP) — The suspect in a torture killing in Alaska’s biggest city ended up leading police right to him, first by losing a digital memory card labeled “Homicide at midtown Marriott” that contained video of the dying woman.

Then came an even more innocuous blunder: He spoke on the tape in his distinctive, very un-Alaska accent.

When a woman found the memory card on the street and turned it over to police, what detectives saw was horrific. At one point, the suspect complained to the victim, whose face was swollen and bloodied: “”My hand’s getting tired.” He then stomped her throat with his right foot.

Amid the footage, a clue: The killer spoke in an “English sounding accent,” and detectives recalled Brian Steven Smith, a 48-year-old South African, from another investigation, the details of which they have not disclosed.

They arrested Smith, who has pleaded not guilty to the September killing of 30-year-old Kathleen Henry, a homeless Alaska Native woman. During his interrogation, police say he confessed to killing another Alaska Native woman.

Anchorage has a diverse population — more than 200 languages are spoken in the school system — and it’s not uncommon to hear people speaking with Russian, Yupik or Hmong accents.But South African accents aren’t common, certainly not after the summer tourist season.
