A severly autistic Westborough boy who drowned in a murky pool at his apartment complex Sunday had been seen in the past walking alone around the spacious facility, authorities said. “We were told by maintenance crews at the complex that this child had been on his own wandering around before,’’ said Alan Gordon, Westborough Police Chief, in a telephone interview Monday.
