Rafiou Sow, the primary suspect in the 2007 murder of Canadian Rachelle Wrathmall, was arrested Friday evening at his home in Conakry, Guinea, according to local reports. The arrest comes nearly 19 years after Wrathmall’s death in Lennoxville, Quebec. While Guinean authorities have not yet officially confirmed the arrest, it follows an announcement earlier this week of a judicial investigation into Sow. A recent report by *La Presse* detailing the cold case is believed to have spurred renewed interest and the investigation. Sow, 49, a political party leader, is currently in custody and being questioned regarding the circumstances of his wife’s death. Quebec police have long considered Sow a person of interest, noting his suspicious departure from Canada shortly after Wrathmall’s death and his unusual behavior at the airport.
