Mother, Boyfriend Suspected in Toddler Killing

Police have identified the two suspects in the killing of a toddler who was found dead on Monday.

Las Vegas Metro Police say the boy's mother, 20-year-old Cassie Smith, was involved in the killing with her boyfriend, 40-year-old Joshua Oxford.

Smith reported 3-year-old Daniel Theriot missing on Sunday morning. She told police he had gone missing at the park, but officers said her story didn't check out. The boy was found Monday near Lake Mead.

Police also said Smith's other son, a 2-year-old, showed signs of child abuse and was taken into the custody of the department of child services.

Smith and Oxford face one count of child abuse related to the younger sibling, but will likely be charged with murder.
