Melissa Huckaby arrested for killing 8-year-old Sandra Cantu

Police have arrested a Sunday-school teacher in the killing of California 8-year-old Sandra Cantu, authorities said early Saturday.
Melissa Huckaby was arrested on charges of kidnapping and murder, according to Tracy, California, police Sgt. Tony Sheneman.

Police would not reveal what led to Huckaby's arrest, but said it followed questioning. They did not offer a possible motive.

Huckaby lived in the same mobile home park as Sandra's family, and Sandra was friends with Huckaby's daughter, Sheneman said.

Sandra's body was found Monday, stuffed into a suitcase in a dairy-farm pond. The girl, from Tracy, had been missing since March 27. The suitcase that held Sandra's body belonged to Huckaby, Sheneman said.
