ABC News has obtained and shown the videotape that prosecution claims shows that Michael Jackson's associates were keeping track of the Arvizos.
The videotaping of the Arvizos was conducted in the days following their departure from Neverland. Private detective Ed Santiago is claiming that he and a friend were hired to watch and follow the Arvizos, and to make sure that Janet Arvizo returned to Neverland and did not try to sell her story to tabloids.
He is quoted as saying:
"It is my understanding that there was some concern about her stability, her emotional stability, and her movements and the people she was interacting with, specifically the tabloids,".
The tape has been shown in court.
