Alcenti's cause of death was ruled starvation. Sweeting and the other children survived.
Calvin and Najlaa McIntosh were arrested on charges including multiple counts of murder and child cruelty. Calvin McIntosh was also charged with several counts of rape, sodomy and incest. Both have been indicted and are awaiting trial. No dates have been set, Assistant District Attorney Rich Vandever said Monday.
The lawsuit filed Thursday names Extended Stay America, three partner companies, five "John Doe" staff members and Calvin McIntosh as defendants. It accuses the hotel of negligence, saying it should have been able to prevent -- or at least stop -- what was taking place.
"Decedent Alcenti McIntosh was born in a hotel room at the Premises in or about August 2013," the suit, which asks for a jury trial and unspecified monetary damages, says. "She was confined in a hotel room at the Premises for her entire life with at least six other people."
