One year ago, on September 7, 2018, rapper Mac Miller was found dead in his San Fernando Valley home. He was 26 years old. At the time, tributes came pouring out from fellow musicians, friends, and fans alike.

Over the past 12 months, more has come to light about Miller's death, which was ruled an accidental overdose from a mix of fentanyl, alcohol, and cocaine.

On Friday and Saturday, fans have been commemorating the rapper's life with heartfelt tweets, a festival celebrating his life, and even tattoos.

Fans were heartbroken when Miller died, and people are still feeling the effects a year later.

People came together at the "Second Annual Mac Miller Celebration of Life," a vigil at one of Miller's favorite spots, Blue Slide Park, to sing his songs and share memories and art.

Miller's father was even reported to be at the festival.

An onlooker quoted Miller's father on Twitter as saying "we finally caught the motherf-----," likely in regards to the arrest that was made on Wednesday. Cameron James Pettit was arrested for allegedly selling the "Self Care" rapper counterfeit drugs that led to Miller's death.

A Drug Enforcement Agency affidavit alleges that Pettit, 28, sold Miller counterfeit oxycodone pills that were laced with fentanyl, an opioid 50 times more powerful than heroin.

Fellow musicians also posted on social media about Miller, including close friend Kehlani, who shared a photo on her Instagram story.
