They were tailing Scott, and realized his change of appearance might mean he would flee the country. (Could have been because he wanted to go public in-cognito, who knows for sure).
Since Scott has been unwilling to speak with Laci's family for months, I think NOW, the Rocha's are going to sit across that cold table from him, look him in the eye and say "WHY, Scott, WHY?". They can't wait.

They said they had seen Scott in the past 2 weeks & saw his bleached hair. Scott told them he had been swimming in a friend's pool and water bleached his hair.
Also said Scott called them after he was arrested, however, they did not say what was discussed.
