Police officials said the 13-year-old boy, later identified as Derek, reportedly admitted to stabbing his 39-year-old mother, Irina, while she slept next to her 14-day-old baby daughter.
Police officials said the son is charged as a minor, but police identified him because he faces a felony, murder in the second degree.
The 13-year-old boy called 911 and told the dispatcher that he stabbed his mother to death. The teen called right away and turned himself in over the phone.
