A donut shop manager in North Philadelphia was shot and killed during a robbery early Saturday morning. A reward has been offered by Philadelphia police for any information on the tragic robbery of Dunkin' Donuts on Saturday.

According to a police statement, Christine Lugo, 41, was opening the business minutes before 5:30am when a man entered and pushed her inside with a revolver to her head, PEOPLE reported.

The description of the criminal is provided by the police to be a man in his mid-30s to 40s with a mustache and goatee and a medium to stocky build. The individual was dressed in a blue zip-up hooded sweatshirt, grey cargo trousers, light grey New Balance sneakers, and a blue mask and gloves with an analog watch on his right wrist.

According to CBS 3 Philly, the man ordered that the 41-year-old woman hand over money in the office. Although she obliged and did what was asked of her, he allegedly shot her in the head, leading to her death. According to authorities, the individual is wanted for homicide. No weapons have been recovered from the site of the crime. The probe is still ongoing.

The Philadelphia police released a surveillance video of the homicide to help the public identify the man and alert the legal authorities if found in the neighborhood.

Dunkin' Donuts released a statement to WPVI after the incident. "We are aware of the tragic incident that occurred at the Dunkin' Donuts on Philadelphia's Lehigh Street. The death of a restaurant manager has grieved all of us at Dunkin', and our thoughts go out to her family and friends".

The victim's son, Christian Lugo said that his mother had relocated to Philadelphia from Boston but that she eventually wanted to return to be closer to her family, which included Christine's daughter and two grandkids.

Regulars at the donut shop remembered Lugo for her kindness and warmth. "She started this thing about paying for the person behind you," Randall Fleming, a customer said. "I'm not a rich man, but I would find out how much it would cost for their coffee or doughnuts or whatever they got, and I would pay for it behind me, and I got that from Christine."
