UTICA, N.Y. (WKTV) - He told police and prosecutors they had the wrong guy, and it turns out, they did. Omar Thompson was under arrest for the murder of Mark Dukette of Camden, and for shooting a second victim who survived.

The Oneida County District Attorney now says that Thompson had nothing to do with the crime.

The woman who survived that shooting on Oneida Street in early March was adamant when she picked Omar Thompson out of a photo array. We saw her testify at a felony hearing and she said Omar Thompson was absolutely the man who shot her and killed her friend.

Last week when prosecutors went to put this case to a grand jury for a possible indictment, Jeannie O'Brien was not so sure. About that time, prosecutors got phone records they had requested and those lead to another man, Mark Anthony-Ware. New York City Police found him and investigators from Utica went to a Manhattan precinct to meet up with him. Now he is under arrest for Mark Dukette's murder. Oneida County's District Attorney says his investigators spent the past week doing something they do not normally do: clearing their original murder suspect.

"I'm just happy that we were able to develop this information and exonerate Mr. Thompson, clear him at this point, clear him before he spent any more time in jail," said Oneida County D.A. Scott McNamara.

How could this woman misidentify the man who shot her and killed her friend? The answer might lie in the police photos as Thompson bears a resemblance to Mark Anthony-Ware.
