Five bodies discovered in Houston’s bayous over five days have sparked online speculation about a possible serial killer.

Social media users have linked the deaths, but Houston police say the cases are unrelated and stress that each cause of death will be determined by autopsy.

Authorities emphasize that the circumstances differ in each case and warn against jumping to conclusions, Chron has reported.

Still, the city’s history with infamous killers like Dean Corll, the “Candy Man,” and the “Texas Killing Fields” cases has amplified public anxiety.

Investigations remain ongoing.
