His neck was broken, he had scratch mark on his neck. He was murdered. There is a theory that he was killed by betting mafia, consisting of mostly pakis. There may be atleast 5 of them. 2 were deld his hand, 2 held his leg, 1 was reading some verses from a book,"hulla mulla maqsood fardoon something something"!!!, and finally 1 was the executioner. The mob boss may have called and said "humko woolmer ka cheekh sunna hai". The executioner may have called the boss on speaker and then strangulated woolmer. Disclaimer: This is just a theory and may or may not coincide with the actual events.
