SOLANO COUNTY — A Vacaville man was arrested Tuesday an infant in his care was found to be under the influence of marijuana.

Jonathan Velasquez Sr., 22, was booked into Solano County Jail on suspicion of felony child endangerment.

The incident came to light last Thursday, when the University of California, Davis, Medical Center in Sacramento alerted Child Protective Services that a 1-year-old boy in their care had either inhaled or ingested the drug. CPS then notified Vacaville police, who assumed the investigation.

The boy and his 2-year-old brother were removed from their south Vacaville home and have since been placed with relatives, Sgt. Charlie Spruill said.

The baby required immediate medical attention, Spruill said.

"We have determined that it was not accidental," the sergeant added.

Velasquez was subsequently identified as the suspect in the case and was arrested. The suspect, Spruill said, admitted that he liked to use drugs but did not safeguard against the drugs falling into the hands of his children.
