When they returned home later that night, Lyle called 9-1-1 and shouted "Someone killed my parents!" When officers from the Beverly Hills police department arrived, the brothers told them that during the murders, they went to a movie theater to see "Batman", and then attended the annual "Taste of L.A." festival at the Santa Monica Civic Auditorium. The police did not order the brothers to undergo gunshot residue tests to find out whether they had recently used a firearm, since, at that time, a lack of evidence prevented them from looking into the brothers more thoroughly. In the months after the murders, the brothers began to spend money lavishly, adding to suspicions that they were somehow involved in the murders of their parents. Lyle bought a Rolex watch, a Porsche Carrera, and Chuck's Spring Street Cafe, a Buffalo wing restaurant in Princeton, New Jersey, while Erik hired a full-time tennis coach and competed in a series of tournaments in Israel. They eventually left the family mansion unoccupied, as they decided to live in adjoining condos in nearby Marina del Rey. They also drove around Los Angeles in their deceased mother's Mercedes-Benz SL convertible, dined expensively, and went on overseas trips to the Caribbean and London. It is believed that they spent somewhere around $700,000 during the period between the murders and their arrests.
