Welsh performed with the band from 1998-2001. During that time, they released the self-titled Weezer, which had the hits ‘Island in the Sun’ and ‘Hash Pipe’. He left in August of 2001 due to a nervous breakdown and was therefore replaced by Scott Shriner. He then began his career as a visual artist and continued to pursue it until his untimely death.
On September 26, Welsh left a chilling tweet on his account: “dreamt i died in chicago next weekend (heart attack in my sleep). need to write my will today”, then, “Correction--the weekend after next.”
The Chicago Tribune reported that Welsh was pronounced dead at 2:50 pm at the scene with narcotics suspected to be the cause. Prescription drugs were found in his room along with a zip-lock bag filled with a white powder substance, suspected to be heroin.
Scott Shriner took to Twitter to say, “ Really bummed about Mikey. My heart goes out to his family and friends. Such a talent” and “ He made a special mark on the world with his art.” The band also tweeted, “We are shocked and deeply saddened to hear the awful news, our friend and our fellow weez rocker @mikeywelsh71 has passed away. We love u Mikey.”
Welsh was expected to attend Weezer's Chicago show RIOTfest that Sunday.
There will be an autopsy conducted and police are investigating his death. This leaves people to wonder if this was premeditated by him or was it just a coincidence. Regardless, it is extremely saddening to see great talent pass too early. Our thoughts and prayers go out to all his family and loved ones.
