Puzzling number of men tied to Ferguson protests have died

Six young men with connections to Ferguson protests have died, drawing attention on social media and speculation in the activist community that something sinister is at play

FERGUSON, Mo. -- Two young men were found dead inside torched cars. Three others died of apparent suicides. Another collapsed on a bus, his death ruled an overdose.

Police say there is no evidence the deaths have anything to do with the protests stemming from a white police officer's fatal shooting of 18-year-old Michael Brown and that only two were homicides. But activists and observers remain puzzled, especially since people involved in the protests continue to face harassment and threats.
