FOX LAKE, Ill. — An elderly man was shot and killed inside his Fox Lake home Monday night.

At around 9:35 p.m., police responded to a residence in the 0-100 block of Mineola Road on the report of shots fired.

When they arrived, officers located a 77-year-old man, later identified as Roy Hoffman, shot to death inside his home.

Police said the 911 caller told dispatchers that a man and woman entered a minivan and fled following sounds of shots fired.

Police believe Hoffman invited the woman, later identified as Kathryn Deason, 31, over to his home “to have a romantic relationship in exchange for money.” While she was there, the man, later identified as Azmi Ibrahim, 37, entered the home and allegedly shot the 77-year-old.

The two then fled.

A short time later, Round Lake officers saw the minivan, noting police were familiar with Ibrahim. A perimeter was set up at his residence in the 300 block of Lunar Drive.

He surrendered to police and is in custody. Ibrahim was charged with first-degree murder and obstruction of justice. Deason was charged with obstruction of justice.

Police believe the shooting was targeted. Anyone with information can contact the Lake County Major Crime Task Force or Fox Lake police.

“Investigators are still looking into that to determine if this was some type of robbery attempt or theft of money attempt, or not providing whatever was agreed upon but taking the money instead,” said Lake County Major Crime Task Force spokesman Christopher Covelli. “There are a lot of theories still being investigated and fine-tuned, but what we do know was that Azmi completely and unnecessarily shot and killed the 77-year-old man.”

Additional charges are possible, authorities said.
