Shortly thereafter, police arrested Kastenberger on a train at Wien Westbahnhof based on descriptions provided by the bank's employees.
His largest haul occurred on March 21, 1988, at a Länderbank branch in Vienna, where he stole two million schillings (approximately €145,000).
On August 13, 1985, the same day he committed his first bank robbery after being released from prison, Kastenberger shot and killed Ewald Pollhammer, a 28-year-old man from Upper Austria.
During the investigation, authorities found two keys in his apartment for safe deposit boxes containing nearly 5.5 million Schillings (approximately €400,000).
Two days later, during his confession proceedings, Kastenberger jumped out of a first-floor window, landed on the hood of a parked car, and escaped.
Kastenberger noticed the police, pulled over to the guardrail, and fled through the woods, where he stole another vehicle in Waasen and escaped via the West Highway.
