small knife or pocketknife and just reached around and slit the driver's throat. The bus rolled over with the driver's side on top; Igrić toppled through the windshield and died on impact. Six other people also died in the crash. The driver was able to crawl out the window and run about up the highway to get help. The 39 passengers of the bus were all sleeping at the time and were all injured in various ways. Twenty-one passengers were treated at hospitals and released. Nine were hospitalized in stable condition, and three were in critical condition. Greyhound response Media attention to this event was intense, with suggestions of terrorist activity. The United States was on edge since only weeks before, the September 11 attacks had happened. A temporary nationwide shutdown of the Greyhound bus service was put into effect. No extra security measures were immediately taken in response to this incident. However, following a very similar incident almost a year later, Greyhound Lines installed partitions on most of its newer coaches that, even if forced open, would prevent someone from easily reaching the driver directly. Attacker Igrić was born in 1972 in Slavonski Brod, Yugoslavia (now Croatia). During his late teenage years he trained as a locksmith in vocational school. He joined the Croatian army in 1991, when he was 19, and was discharged in 1993, after what the ambassador of Croatia, Ivan Grdešić, described as "violent behavior and substance abuse... he was connected with crimes in Croatia." When ethnic tensions began to flare during the mid-nineties he joined others in Croatia's "homeland war" of independence from Yugoslavia. Igrić, a citizen of Croatia, entered the United States through the city of Miami, Florida during March 1999, on a 30-day transit visa. He overstayed the visa by two years, convincing US immigration officials he had relatives in Florida and New York. He worked in a restaurant in New York City before the Greyhound incident. Igrić had a long history of mental illness.
