Karlene Ann McCaffrey, receptionist for Sebring, Inc. told authorities that Rostau had delivered narcotics to the Tate residence on the night of the homicide. Rostau informed McCaffrey that he had delivered cocaine and mescaline to the house but that Frykowski and Sebring wanted some additional narcotics and that he had gone back down the hill but was unable to locate the other narcotics they requested and therefore he did not return to the Tate residence. McCaffrey stated that on August 7, 1969, she had talked to Sebring and he had informed her that he had been burnt on $2,000 worth of bad cocaine. McCaffrey stated that in her opinion Sebring would do almost anything to get back at the person who had burnt him.
Rostau was later charged with interstate theft of securities from the mail at Kennedy Airport. He was found shot to death in a parked car at that airport. The car had been rented in Boston and driven to New York at least 12 days before his body was found.
