Many of them died in the final days of the war since it was all hands on deck (the Russians especially weren't very forgiving). Higher rank ones that had socked away money and resources fled into hiding in South America and elsewhere (even the US) and were hunted. Many of them were caught and either killed covertly by the Israelis or charged.
But at this point in 2017, it's been 72 years since the war ended. So even a low-ranking 18 year-old at the time of the war would be 90 at this point. Most of the serious offenders were older at the time of the war, so they are probably all dead now one way or another.
