Looking For Bones, Just Not That Kind

City kids are smart enough to know that when you see an unattended suitcase, nine times out of ten it contains money of some dubious provenance. But on that tenth time:

Four children playing in a Queens park Tuesday stumbled upon a suitcase filled with human bones, a police source said.

A skull, a spine and several other bones packed in a blue rolling suitcase were found about 4:30 p.m. in Forest Park in Woodhaven, cops said.

“They dragged it out . . . and opened it up and took the skull out,” a source said. “They thought maybe there was some money in [the suitcase]. What a surprise.”
