WARSAW, Nov. 9 (Xinhua) -- Investigators found four firearms and about 500 rounds of ammunition on the Krakow gunman and in his car, Polish news website Onet reported Monday, citing National Prosecutor's Office spokesperson Przemyslaw Nowak.
The four firearms included two AR-15 rifles and two pistols, Nowak said. The ammunition found on the gunman and in his car included rounds for those weapons and could have been used for further shooting.
Investigators also recovered a large number of spent cartridge cases, Nowak said. At least dozens of shots, and possibly hundreds, were fired during the incident in Krakow. The exact number will be determined after prosecutors and police analyze material collected over the weekend.
The gunman drove into Krakow's Main Market Square on Saturday afternoon and fired at random passersby before being shot and detained by police. Officials said Saturday evening that six people had been killed and 16 others injured, including two police officers and the gunman.
The gunman died in hospital early Monday, local police said. ■
