GARY, Ind. (WLS) -- The mother of an Indiana man killed in an officer-involved shooting says the Gary Police Department's story doesn't add up.Rashad Cunningham's family has hired a lawyer in hopes of getting answers after the 25-year-old was fatally shot outside his Gary home early Saturday morning.Authorities have only released limited information on the police-involved shooting at East 23rd Avenue and Kentucky Street, which officers said occurred while conducting a traffic stop."I want to know why you killed my son. I want to know what measures made that happen," said Tonia Simmons, Cunningham's mother.Cunningham's girlfriend, Heather Fox, said she sent a letter Sunday to Gary Mayor Karen Freeman-Wilson, demanding to view any police video of the shooting."They are not telling me nothing, nothing at all. They're not saying nothing," said Fox, who's also the mother of his youngest child.Cunningham leaves behind five children, including a 1-year-old."For them to not answer any questions is not fair to me," said Simmons. "It's not fair to his family. It's not fair to his children."The family is being represented by civil rights lawyer Andrew Stroth."He was in the front of his house parked in a car when, according to two eyewitnesses, the police approached the car and, without any provocation by Rashad, shot five to six shots into the vehicle, tragically killing Rashad Cunningham," Stroth said.Witnesses said Cunningham had a gun on his lap during the encounter with police, but they allege that he wasn't reaching for the weapon.
