A homicide investigation has begun in Davis into the death of a toddler.

19-month-old Cameron Morrison died Saturday after being rushed to the UC Davis Medical Center last Wednesday.

The Davis Police department says the boy's mother approached an ambulance crew at a coffee shop just before midnight on Wednesday asking for help.

The child was unconscious at the time.

The crew began giving aid and took him to UC-Davis but he eventually died because of the injuries Saturday afternoon.

Darnell Dorsey, 21, was arrested on suspicion of child endangerment.

He was arraigned Monday but did not enter a plea.
