The suspect reportedly left the school property, got into a blue Dodge Charger, and was later arrested at his home about a half-mile away, KTRK reported. The suspect has no known affiliation with the school. He was arrested on Wednesday night and booked into the Harris County Jail. One neighbor was inclined to think that there was a misunderstanding, describing the suspect as a friend and veteran."He watches my kid all the time for me. When I was in California and gone for a couple of months, my son would come home, and he would go to the bus stop and walk him home, put him in the house, let him sit in there, he could go across the street and get the neighbor, you know what I mean," the man, identified only as Randy, told KTRK.Like Blaze News?
