CENTENNIAL — Sir Mario Owens was a cold-blooded killer who ambushed a witness scheduled to testify against Owens’ best friend, prosecutors said Friday during closing arguments.
The five-week trial for Owens, accused of killing Javad Marshall-Fields and his fiancee, Vivian Wolfe, in June 2005, is in the hands of the jury, which will begin deliberating Monday morning.
If convicted, prosecutors have said they will ask for the death penalty against Owens.
Marshall-Fields was scheduled to testify against Owens’ friend, Robert Ray, in the death of another man a year earlier at Lowry Park in Aurora.
Marshall-Fields was killed on the eve of that trial.
Ray and Owens have already been convicted in that case.
Owens received life in prison without parole in the shooting death of Gregory Vann at the park. Ray was sentenced to 108 years in prison.
