Nicholas Spencer and Mackenzie Leigh Mathias Spencer, both 32, were arrested and charged earlier this month with aggravated torture, which carries a life sentence if convicted, for alleged abuse spanning two years.This week, they were also charged with aggravated child trafficking, which carries the death sentence if convicted, Joan Keko, an attorney with the Ugandan state prosecutor's office, confirmed to ABC News.The two are being detained at a maximum-security prison in Luzira, a suburb of the capital of Kampala, and were not granted bail after being determined a flight risk, Keko said.The couple allegedly "constantly tortured" the foster child between 2020 and 2022, which "attracted the attention of neighbours," who notified Kampala Metropolitan police, according to a statement from the Uganda Police Force.Police received video evidence from a neighbor and nurse who were checking on the child, a Kampala police source told ABC News."
