The Mystery of Elisa Lam

She walked into the hotel… …but no one ever saw her walk out. Elisa Lam,

21 years old, checked into the Cecil Hotel in Los Angeles in 2013. She was last seen

on security footage acting… strangely. Pressing elevator buttons that didn’t work.

Peeking into the hallway, like someone was chasing her. Days later,

hotel guests complained the water tasted weird. Maintenance opened the rooftop water

tank… …and found her body inside. The tank was locked. The alarm never

went off. No camera ever showed her going up there. So how did she get in?

To this day — no one knows.
