LUDINGTON, Mich. -- The body of a missing 12-year-old girl has been found, police said Monday.

The FBI, state police, Ludington police and Mason County Sheriff's Department were involved in the search for Sabrina Dalzell, who last was seen late Friday at her home and was discovered missing early Saturday.

An arrest was made in connection with the case, Ludington police said.

An Amber Alert for Sabrina that had been issued Saturday was canceled Monday.

More than 200 firefighters, police officers, family members and other volunteers searched for her Sunday in an area near Lake Michigan. Police were holding a 30-year-old ex-convict known by the child's mother for questioning.

Ludington police scheduled a news conference for 1 p.m. EDT to discuss the case.

Barnett said Sabrina's mother, Amanda Dalzell, left Sabrina and her 10-year-old brother at home at about 11 p.m. Friday while she went out socially. She discovered the girl was missing at about 7 a.m. Saturday. The police chief said the boy was asleep through the night and didn't appear to know anything about his sister's disappearance.

Barnett said authorities "don't have any reason to believe" Sabrina left on her own, but are considering all possibilities. He said her family is cooperating with the investigation and several relatives had joined other volunteer searchers.
