Brown’s old employer said last month that the victim would be greatly missed.

“People loved Gary Brown, and what I know of (Lee) — mild-mannered, quiet, nice Asian woman,” said Charles Hardwick, who is employment manager of Howard Area Employment Resource Center, where Brown worked. It’s where Brown met Cathy Lee, who was doing some research a few years ago and came to the office to use the computers.

Pratt was arrested Monday at O’Hare International Airport, after he was found driving Lee’s car, police said. He was also found to be carrying credit cards belonging to both Brown and Lee and had used the credit cards after he allegedly killed them.
