Police, FBI seek public's help in finding motive behind Las Vegas massacre

LAS VEGAS – Baffled police and FBI agents, still lacking a clear motive for the Las Vegas massacre of 58 people by a lone gunman five days ago, appealed to the public on Friday to come forward with any information that might help solve the mystery.

Clark County Undersheriff Kevin McMahill said investigators remain largely in the dark after running down more than 1,000 leads seeking clues to what drove a wealthy retiree with a penchant for gambling to carry out the deadliest mass shooting in modern US history.
