Streamwood police released new surveillance video Tuesday of a man they believe killed a gas station clerk in a robbery nearly a year ago.
Anandkumar "Andy" Jaiswal, 24, was fatally stabbed early March 16, 2013, as he was working the overnight shift at Thornton's gas station, 2 N. Barrington Road in Streamwood.
The brief footage shows a suspect who "went to great lengths to avoid detection and conceal his appearance," Police Chief James Keegan said. The man was wearing a hood, mask and black clothing, with one white shoe and one dark-colored shoe. The segments show the man -- described as light-skinned and between 5 feet 8 inches and 6 feet tall -- walking through the gas station before and after the stabbing, police said.
Police hope the suspect's gait and mannerisms in the video lead to new information on the crime. A reward also has increased to more than $27,000.
"Too much time has elapsed since this brutal crime took place," Keegan said.
Jaiswal worked extra hours at the gas station as the sole bread winner for his family, who came to the area from their native India about four years ago. He hoped to create a better life for his family and pursue his dreams of working with computers, police said.
Keegan called him a "docile, quiet and unassuming victim" who put up no resistance to the killer.
"Instead, he was cooperative with the suspect's demands before being viciously attacked and unnecessarily killed," Keegan said.
Forensics specialists and other analysts enhanced the images in the video, police said.
"Someone out there heard something, and someone out there knows something," Keegan said.
