Robert's aunt, Trisha Burrill has been acting as the family's spokeswoman. She told ABC's Boise affiliate KIVI that the family's troubled history should not be a focus for police or the media.
"We do not know why people think any of this matters," she said. "We are asking everyone to stay focused on our target on hand and that's to bring Robert home."
KIVI reported today that Boise police spent hours at Jenkins' home Thursday, towing the family's car and leaving with bags of evidence.
Robert was reported missing shortly after 10 p.m. July 24. He was last seen wearing a faded blue T-shirt with a Superman design, blue jeans and dark tennis shoes.
Hightower told ABCNews.com that about 140 registered sex offenders live within a two-mile radius of Robert's home in a working-class neighborhood of the city and that each one has been visited.
"Some of them have been checked and rechecked and rechecked," she said.
