ALBUQUERQUE, N.M. (AP) — A man accused in the beating death of a New Jersey resident he claimed sexually abused him as a child has been charged with killing his ex-wife and two others in New Mexico in what investigators call a complicated case spanning multiple states. The charges Friday come about a week after investigators searched a house where Sean Lannon, his ex-wife and their children lived in the city of Grants. The remains of Jennifer Lannon, two of her friends and an Albuquerque man were found earlier this month inside a vehicle at an Albuquerque airport parking garage. Charges related to the death of the Albuquerque man have yet to be filed.
