Family and friends of those who were killed and injured in a crash that involved an Indianapolis police officer spoke out Tuesday after hearing that blood samples taken from the officer were mishandled by police.Eric Wells was killed and Kurt Weekly and Mary Mills were injured in the Aug. 6, 2010 crash in which investigators said suspended Indianapolis police Officer David Bisard struck a group of motorcyclists stopped at a red light.Indianapolis Police Chief Paul Ciesielski stepped down on Tuesday after details of the discovery were released.George Burt was riding his motorcycle with Wells and said he witnessed the crash, RTV6's Eboné Monet reported.How can a person describe when you see a person who is right there with his bike and two other people lying on the ground who you were just talking to moments ago? Burt said.In a phone interview, Wells mother, Mary Wells, said she thinks Marion County Public Safety Director Frank Straub should resign along with Ciesielski.The fact that a (intoxicated) police officer on duty hit and killed my son and injured two others is wrong. Do I accept (Bisards) apology? No. Do I want his apology? No, I want justice, Wells said.Attorney Bruce Kehoe, who represents Weekly, pointed to several mishaps within IMPD."How many catastrophic mistakes can you have in one case?" Kehoe said. "It seems to me that they need to address a systemic issue that exists between IMPD in terms of the management, the chain of command and the (Fraternal Order of Police)."Family and friends of the victims have planned a memorial in August to mark the second anniversary of the crash. All proceeds will be donated to charity.
