Police released new information from West Haven on the death of a 4-year-old pulled from a hot car.

They say surveillance video shows Dusan Jenkins and his 2-year-old brother Davion getting into the family car on their own after leaving their apartment by themselves.

Dusan died a few hours after being discovered by his father.

Davion was taken to the hospital but is now back home.

Police say it's unclear if their father even knew the boys had left.

No charges have been filed as the investigation continues.
