The police investigated these claims and during a search of the Texas School Book Police Depository they discovered on the floor by one of the sixth floor windows, three empty cartridge cases. They also found a Mannlicher-Carcano rifle hidden beneath some boxes. At 1.16 p.m. J. D. Tippit, a Dallas policeman, approached a man walking along East 10th Street. A witness later testified that after a short conversation the man pulled out a hand gun and fired a number of shots at Tippet. The man runs off leaving the dying Tippet on the ground. Twenty minutes later, Johnny Brewer, a manager of a shoe shop, saw a man who appeared to be hiding from passing police cars. He called the police after he saw the man enter a cinema. When the police arrived Brewer accompanied the officers into the cinema where he pointed out the man he had seen acting in a suspicious manner. After a brief struggle the man was arrested. His name was Oswald. The police soon found out that Oswald worked at the Texas Book Depository. They also discovered his palm print on the Mannlicher-Carcano rifle that was found earlier that day. Other evidence emerged that suggested that Oswald had been involved in the killing of the president. Oswald's hand prints were found on the book cartons and the brown paper bag. Charles Givens, a fellow worker, testified that he saw Oswald on the sixth floor at 11.55 a.m. Another witness, Howard Brennan, claimed he saw Oswald holding a rifle at the sixth floor window. The police also discovered that the Mannlicher-Carcano rifle was purchased under the name A. Hiddell. When he was arrested, the police found that Oswald was carrying a forged identity card bearing the name Alek Hiddell. The rifle had been sent by the mail order company from Chicago to P.O. Box 2915, Dallas, Texas. The Post Office box belonged to Oswald. While being interrogated by the Dallas Police, Oswald denied he had been involved in the killing of Kennedy.
