'When I Die You'll Love Me': See Lil Peeps' Eerie Final Instagrams

Lil Peep was found dead on his tour bus late Wednesday ahead of a scheduled concert in Tucson, Arizona, Sgt. Pete Dugan confirms to PEOPLE

In the days leading up to his sudden death, emerging rapper and YouTube star Lil Peep shared a series of grim Instagram posts with his 1.3 million followers.

Lil Peep was found dead on his tour bus late Wednesday ahead of a scheduled concert in Tucson, Arizona at The Rock nightclub, Sgt. Pete Dugan of the Tucson Police Department confirmed to PEOPLE on Wednesday.

"Based on information they were told and evidence that was found in the tour bus, they had evidence of a possible drug overdose, most likely from Xanax," said Sgt. Dugan.

On the day of his death, the 21-year-old rapper took to social media to post an eerie photo from a recent concert with the caption, "When I die You'll love me."

And just hours before his death, he shared a photo with his followers with what appears to be pills or tabs on his tongue, writing, "f— it."

Peep's manager Chase Ortega broke the tragic news via Twitter Thursday morning. "I've been expecting this call for a year. Mother f—," he wrote.

In another social media post, Lil Peep revealed he relies on pills to "be happy."

"I just wana be everybody's everything I want too much from people but then I don't want anything from them at the same time u feel me I don't let people help me but I need help but not when I have my pills but that's temporary one day maybe I won't die young and I'll be happy? What is happy I always have happiness for like 10 seconds and then it's gone. I'm getting so tired of this," Lil Peep wrote in a caption for a video of himself smoking a cigarette with a friend.

Another video shows him attempting to drop an unidentified pill into his mouth several times before giving up and pushing it into his mouth, swallowing it and shaking a prescription bottle that appears full of pills.

In another video posted to his social media, Lil Peep danced to Green Day's "American Idiot" and bragged about his drug use, captioning the post, "I just took honey and shrooms."

While he never made it to his Come Over When You're Sober tour show Wednesday night, the rapper met with fans and took pictures in the hours before his death.

"Look at my beautiful fans awwwww," he wrote on his last Instagram photo.

Inside the club, fans had their eyes set on opening acts, but became worried as they were moved out of the club after paramedics arrived on scene. Sarah Stennett, CEO of First Access Entertainment, who partnered with Lil Peep in early 2016, released a statement about his death.

"I am shocked and heartbroken," she wrote."I do not believe Peep wanted to die, this is so tragic. He had big goals and dreams for the future which he had shared with me, his team, his family and his friends. He was highly intelligent, hugely creative, massively charismatic, gentle and charming. He had huge ambition and his career was flourishing. I have spoken to his mother and she asked me to convey that she is very, very proud of him and everything he was able to achieve in his short life. She is truly grateful to the fans and the people who have supported and loved him."
