After pleading guilty to the starvation death of his 15-month-old daughter, 48-year-old Calvin Mcintosh could spend the rest of his life behind bars.

According to Fox News, the Georgia man was in court this week when he pleaded to charges including felony murder and first-degree cruelty to children.

He was arrested in connection to a November 2014 incident during which hospital staff contacted authorities to report young Alcenti’s death. Her father reportedly brought her into Northside Hospital in Sandy Springs and medical professionals determined she was dead on arrival.

When officers responded to the hotel room where Mcintosh had been staying, they reported finding a 5-year-old and two 3-year-old children who also showed signs of being “severely malnourished.”

Police soon linked the death to a suspected “case of neglect and abuse,” which they later said could have been inflicted as part of an “Islam-based cult.”

Authorities released a statement indicating that investigators “discovered during the execution of a search warrant, copious amounts of literature and notes in reference to ritualistic behavior and the Nuwaubian Nation of Moors, an Islam-based cult which is known for being a sovereign group.”

A medical examination pointed to starvation as the cause of the 15-month old girl’s death.

Police believe two of the young children found at the residence were the product of an incestuous relationship with his daughter, who was also at the residence.

Another woman was also at the location. Authorities believe she was kidnapped in 2010 and was the mother of the other two children.

Iasia Sweeting was 21 years old when police found her, but she weighed just 59 pounds.

Sentencing in the case is set for November.
