Lock, Frock and Mock(ing bird)

Weirdest workout finding:I was running along and found, within twenty feet of each other, three items.  Help me form the scenario with them from the previous Saturday night. 

Found:  One pair of broken flip flops, one dead bird, one ...what appeared to be... long black dread lock severed from a person's head. 

Exactly.  I was confounded by those three items. 

Have you ever seen odd items while running?

They were found close to the local hospital.
