More details have been released in the deaths of two young Madison brothers.

The brothers are identified as 4 year-old Kevin McArthur and his 3 year-old brother, Kemaury. Police discovered their bodies in a car early Wednesday morning, in a parking lot on Madison’s east side. That was after the suspect in the case, 28 year-old David Hoem, had turned himself in. Hoem is the boyfriend of the children’s mother, and he and the mother had been involved in a domestic altercation on Monday Hoem picked the boys up from their father’s house on Tuesday, the last time they were seen alive.
