Babysitter tells police he's watching abducted child

RENTON, Wash. -- A couple in Washington state were surprised to discover the child they were babysitting had been abducted and an Amber Alert issued seeking the toddler's return.

Authorities issued the alert Tuesday night after the 2-year-old boy was taken from his home in Des Moines. John Truong told KOMO-TV in Seattle that he and his wife had been asked to watch the child by his sister and didn't learn about the alert until Wednesday morning. Truong called police, who retrieved the child.

Truong told authorities his sister asked him to watch the child overnight, explaining it was her boyfriend's son.

Police have arrested the sister in connection with the kidnapping. They say she and the child's paternal grandmother went to the boy's home Tuesday and incapacitated his mother with a Taser. The grandmother was questioned by authorities.
