Girl brings note to school, leading Las Vegas police to find boy's body inside freezer in home's garage

The body of a boy described as preschool-aged was found in a freezer in a Las Vegas home's garage and the mother's boyfriend has been arrested, police said.

Police obtained a search warrant and found the boy's remains Tuesday after a girl took a note to school in which the mother said she was being held against her will and didn't know the whereabouts of her young son and believed he was dead, police Lt. Ray Spencer said during a news conference.

After being contacted by the school, police set up a surveillance operation near the home, CBS affiliate KLAS-TV reported. Around 10 a.m. Tuesday, police saw a man, later identified as Brandon Toseland, and a woman, leave the home. Officers then pulled the car over.
