TikToker Eva Evans appears to have died by suicide … TMZ has learned.

Law enforcement sources tell us a friend found Eva’s body late Saturday night after having seen her alive Friday morning. We’re told the friend had a key to Eva’s NYC apartment and when they went to check on her … they found her hanging inside.

We’re told the friend called 911, and when police arrived … they told police they didn’t know Eva to be depressed or emotionally disturbed — so it’s safe to say it took them by surprise.

When paramedics arrived, they pronounced her dead at the scene.

Our sources tell us there were no unusual injuries … and there was no sign of a struggle. Our sources say a note was left behind, the contents of which are unclear at this point.

Despite the obvious signs of what certainly sounds like Eva taking her life … we’re told her official cause of death hasn’t been ruled on just yet, and is pending toxicology results.

The update comes a few days after Eva’s sister announced her passing on social media. In her tribute, Lila expressed her grief over Eva’s passing … praising the “Club Rat” creator as a sweet and loving sister. She didn’t provide any context or details about her sibling’s death.

Eva was known on TikTok for posting day-in-the-life type content about 20-somethings in New York … and she also famously created a web series called ‘Club Rat’ about the dating scene.

While she wasn’t known for posting about mental health, Eva did share a personal story with an org called Don’t Mind Me … which advocates for folks who are struggling. She revealed her father had died by suicide in 2018 … something he’d threatened since she was a kid.

She was only 29.
