A 17-year-old boy was being held in the Hennepin County juvenile detention center Thursday night in connection with an investigation into the death of his girlfriend's 2-year-old daughter.
Minneapolis police released few details about the case ahead of the official medical examiner's report.
The child's biological father, Max O'Neill, said in an interview late Thursday that his daughter, Sophia O'Neill, died of internal bleeding. O'Neill said doctors at Hennepin County Medical Center told him the toddler had suffered a ruptured kidney and pancreas. The father said he had seen injuries on his child previously that he suspected were the result of abuse and reported them to authorities.
However, the suspect's grandmother described the teenager as a loving caretaker, who frequently took care of the girl while the mother was away.
Just before noon Wednesday, officers responded to an emergency call about a child not breathing in the 3800 block of 30th Avenue S., a residential area southwest of Hiawatha Avenue and E. 38th Street.
The toddler was taken by ambulance to HCMC and later died.
Police would say only that "a juvenile suspect" was arrested in connection with the child's death, declining to release any other details.
Interviewed Thursday night at the home, the suspect's grandmother, who asked that her name not be published, said she was grieving for Sophia.
