SUSPECTS

GARRETSON, William Etson, male Caucasian, 20, 5-7, 154, brown hair and brown eyes, LA 974 580-G

Garretson was arrested in the guest house at 10050 Cielo Drive. He gave vague, unrealistic answers to questions about his observations and recollections of events occurring in the Polanski house between 8-8-69, 0200 hours and 8-9-69, 0930 hours. He was questioned at West Los Angeles jail at approximately 1600 hours, 8-9-69, by investigators. He was advised of his rights and agreed to speak freely without counsel but gave stuperous and non responsive answers to pertinent questions. He retained the services of attorney Barry Tarlow, shortly after the first unproductive interview. He was transported to Parker Center where investigating officers, in the presence of attorney Tarlow, had another fruitless but short interview with the suspect. At this time, it was agreed that Garretson would submit to a polygraph examination on Monday, August 10, 1969, with his attorney representing him at the interview.

On 8-10-69, at 1600 hours, in the company of his attorney and upon his attorney's advice, Garretson submitted to a lengthy polygraph examination conducted by Lieutenant Burdick, S.I.D. Polygraph Section. At the time of this examination, Garretson was more responsive to questions, but gave vague and unsatisfactory responses on questions pertinent to the crime that were asked him at the polygraph interview, prior to the questions being presented to him on the machine.

In the opinion of Lieutenant Burdick, Garretson's answers were generally considered truthful; however, there was an underlying belief by Burdick and the investigating officers that due to some narcotics sedation or other mental incapacity, the subject was not sensitive to all of the monitoring devices employed on the machine.

Investigating officers went back to the crime scene and reviewed the physical and acoustical aspects of the scene as related to what Garretson, who claimed to have been awake all night in the guest house
