Michael Brown

The parents of Michael Brown, the unarmed man whom a Ferguson, Mo., police officer shot and killed last August, have filed a civil lawsuit against the city, along with former police chief Thomas Jackson and Darren Wilson, the now-former officer who shot Brown, 18.

The lawsuit was filed by Michael Brown Sr. and Lesley McSpadden at the St. Louis County Courthouse Thursday morning. It says Wilson "unjustifiably shot and killed" Brown, using "an unnecessary and unreasonable" amount of force.
