Lucker was riding his black 2013 Harley-Davidson south on Main Street in Huntington Beach about 8:55 p.m. Wednesday when he hit a light pole near the intersection of 13th Street.
The motorcycle continued sliding south on Main Street and struck a northbound 2007 Nissan Titan pickup.
Lucker was seriously injured and was treated at the scene by paramedics. He died shortly after 6 a.m. on Thursday at UC Irvine Medical Center.
"He was an alcoholic, and it's a been a big battle," Jolie Carmadella said at last night's candlelight vigil at the crash site, which was attended by 300-400 fans, friends and family members (see video below). "I tried to stop him. I was in front of him begging him not to leave the house. Begging him. 'Just seriously, for us, don't leave.' And he did. And this is what happened.
"It's a wake-up call."
She continued, "He was an amazing man. He was a wonderful father and a great husband. And now he's gonna miss out on watching [his five-year-old daughter] Kenadee grow, because he decided to drink and ride.
"Just don't. Just think before you guys do something stupid. Please learn from this. Please."
The surviving members of SUICIDE SILENCE posted a statement on their Facebook page Thursday morning reading, "There's no easy way to say this. Mitch passed away earlier this morning from injuries sustained during a motorcycle accident. This is completely devastating to all of us and we offer our deepest condolences to his family. He will be forever in our hearts."
