Eagan police said Monday that a 3-year-old boy who was found unresponsive Wednesday was killed.

Zayden Ace Lawson was "subjected to blunt force trauma," authorities said. His death was ruled a homicide.

Just after 3 p.m. Wednesday, officers were called to the 1600 block of Oak Ridge Circle about an unresponsive child. Medical personnel worked to save him but he died later at United Hospital.

No arrests have been made and there is no threat to the community, authorities said.

Police are asking anyone with information to contact the Police Department at 651-675-5700.
