Federal prosecutors have worked out a deal with an American missionary in Nicaragua who may help them find a woman involved in a custody dispute with her former lesbian partner.

Timothy Miller was charged with helping Lisa Miller flee the United States with her 9-year-old daughter Isabella.

Janet Jenkins and Lisa Miller were joined in a Vermont civil union in 2000.

Two years later, Miller gave birth to Isabella.

Later, Miller became a Christian and renounced homosexuality, leading to a lengthy custody battle for the young girl.

Miller fled the country after a Vermont court gave custody to her former partner.

Prosecutors say Miller and Isabella traveled to Nicaragua and were hidden by Timothy Miller and other missionaries.

Their current whereabouts are not known.

Prosecutors have decided to drop criminal charges against Timothy Miller in exchange for his testimony in future proceedings.
