Three Kids Missing After Mother Found Dead

Police issued an Amber Alert for three Humboldt Park kids who've been missing for days. Oscar Casanova, 6, Karla Casanova, 7, and Fernando Casanova, 11, above, were abducted from their school Friday. Their mother was found dead in their apartment yesterday afternoon, and police are treating her death as a homicide. Investigators are looking for Benito Casanova, father to two of the missing children; according to CBS 2, "neighbors now believe...32-year-old Benito Casanova kidnapped [the children] after killing their mother."

Benito Casanova may be in a silver or gray Dodge Dakota with the license plate 86196HB. If you see him or the kids, you should call 911.

In 2006, the last year for which data is available, police issued 261 Amber Alerts; 214 of those cases "resulted in a recovery," according to the Department of Justice report. [DOJ, CBS 2, Trib, S-T]
