INDIANAPOLIS (AP) — A jury has convicted a 21-year-old Indianapolis man of murder, felony murder and robbery in the slaying of a man who advertised the sale of a cellphone on Craigslist.

The Marion County Prosecutors Office says Bryant Dowdy was found guilty Wednesday of the December 2012 shooting death of Nishant Patel at an apartment complex on the city’s east side.

Dowdy is due to be sentenced Thursday.

Dowdy already is serving a 75-year prison sentence after being convicted of the attempted murders of two cousins who were co-conspirators the day after Patel was slain. Patel’s cellphone was found with one of the cousins.

Prosecutors say one of the cousins, Dominique Clanton, has pleaded guilty to conspiracy to commit armed robbery resulting in death. He’s due to be sentenced Friday.Related Story:Police: Ohio man used website to set up armed robberies
