CHICAGO — A man convicted of sexually assaulting and beating a 65-year-old man during a robbery in Grant Park in 2011 will spend the rest of his life behind bars.
Convicted felon Cortez Foster, 47, was sentenced Thursday to life in prison plus seven years, according to Cook County State's Attorney Anita Alvarez.
Around midnight March 25, 2011, Foster approached a man walking through Grant Park and began kicking and punching him, police said. He then pulled down the man's pants and sexually assaulted him with a tree branch. After the attack, Foster stole the man's cellphone and fled, according to prosecutors.
The Chicago Fire Department found the victim covered in blood with no pants on. He was transported to Northwestern Hospital and required surgery, according to prosecutors.
Once police determined the man's identity, they were able to trace the cellphone to an apartment complex. A witness then told police he had traded the phone for three Viagra pills. Police located Foster at the Pacific Gardens Mission, according to prosecutors.
Foster was on parole when the assault and robbery occurred. He has three prior felony convictions, including armed robbery, robbery and criminal sexual assault.
