28 yr old Sunday School Teacher Arrested in the Murder of little Sandra Cantu.

TRACY, Calif. - A Sunday school teacher has been arrested after an 8-year-old girl's body was found in a suitcase pulled from the water, NBC News reported Saturday.

Tracy police Sgt. Tony Sheneman told NBC News that Melissa Huckaby, 28, was held in connection with the kidnapping and murder of Sandra Cantu.

Sources say the suspect is 28-year-old Melissa Huckaby, a neighbor whose own daughter was one of Sandra’s playmates.

Huckaby has been charged with kidnapping and murder.

Earlier Friday, she had told reporters a suitcase had been stolen from her on March 27 -- the day Sandra disappeared. Sandra’s body was found stuffed into a suitcase and dumped in a farm pond.

Huckaby is the granddaughter of the pastor of a nearby church that was searched extensively Friday by police investigators.

Huckaby taught Sunday school at the church, according to The Associated Press.

Soon after that search, Huckaby drove herself to the police station, where she was questioned until early Saturday morning.

Cantu’s disappearance had left the city of Tracy on edge, wondering how a little girl could just vanish so close to home.

The last time her mother saw Sandra alive, Sandra was going outside to play with friends, and surveillance video taken in their trailer park showed Sandra happily skipping on the trailer park's grounds.
