Bengbu, China: A pensioner was confronted by six human heads when she opened a suitcase she found floating on a Chinese lake.

The 68-year-old woman made the macabre discovery after seeing what appeared to be human remains through openings in the case while litter picking in a park in the city of Bengbu.

Police initially thought they were facing a serial murder investigation.

But on closer inspection now believe the body parts are discarded samples from a nearby medical institute, it was reported by Rocket News 24.

The medical centre also conducted its own investigation and said the way the heads had been removed suggested it was likely performed by a research team rather than a killer.–MO
