LAS VEGAS — A police detective asked a Nevada judge Wednesday to keep warrant documents in the Michael Jackson death investigation sealed until Jan. 18.

Los Angeles police Detective Orlando Martinez made the request by telephone before Clark County District Court Judge Valerie Adair closed the hearing to the public.

Adair decided to wait at least one more day before deciding on a media request to unseal the records related to an Aug. 11 search of Applied Pharmacy Services in Las Vegas, where authorities say Jackson's personal physician, Dr. Conrad Murray, bought the powerful sedative propofol.
