Someday, an entire chapter might be devoted to Dino Vicente in the yet-to-be-written "Really Obvious Things Parents Should Never, Ever Do."
According to police, Vicente, 31, drove from Coopersburg, Pa., to Kensington to buy drugs on Saturday.
He had a companion: His 6-year-old stepson.
The trip went according to plan. "He left the kid in the car, went to an unknown location and got high," an investigator said.
Then everything went to pot. About 4:30 a.m., Vicente called the boy's mother to report that he couldn't remember where he had parked his car, the investigator said.
