Palenza was a passenger in a car that was leaving an Albany Avenue gas station just after before 1 a.m. on Feb. 23. 2006 when someone shot at the car.
Palenza was shot in the head and was pronounced dead at Saint Francis Hospital at approximately 10:15 p.m. that night.
On Tuesday, Gov. M. Jodi Rell authorized a $50,000 reward for information that leads to arresting the person who pulled the trigger..
"I sincerely hope that by issuing this reward it may prompt someone to come forward with information that will help police bring this case to a conclusion," Rell said. "I urge anyone with information to come forward and help bring a sense of closure to the family of Ms. Palenza, who has waited nearly three years for justice."
