CHICAGO (CBS) — Friends and family are mourning the loss of a man who was shot and killed at a Northwest Side bar.

Angel Ortiz Jr. was working as a bouncer at Brudder’s Sports Bar in the Old Irving Park neighborhood when a bullet came flying through the building, hitting him in the head on Saturday night.

CBS 2’s Suzanne Le Mignot reports outside the bar there are yellow and white flowers and a white candle in memory of the man who just started working there part-time a short time ago.

Police sources say right before the shooting, two women were kicked out of the bar. Whether that’s related to the shooting still isn’t known. It does appear someone in the bar was targeted.

The bar manager says police told him someone was shooting from an alley across the street from the bar. Some of the bullets hit a van and one of them made it through the bar window.

Brudder’s Sports Bar is offering a $2,500 reward for information leading to an arrest and conviction in this case.

Ortiz’s family has set up a burial fund on youcaring.com. On the site, loved ones describe the 51-year-old husband and father of two boys as an “amazing ball of energy.” They say he just wanted to make sure his family was always taken care of.

The bar will be donating to help pay for the funeral, which will take place this Friday. The manager says the staff is devastated and heartbroken. Ortiz’s brother also works at the bar.

Also Monday, members of the victim’s family held an impromptu news conference.

“To be taken away like this is just senseless,” Ortiz’s sister, Mayra Ortiz-Colon, says.

Ortiz, 51, worked at the bar as a second job.

“What he did to keep us on his back just to give  me the opportunities that I had – so I could go to school and do what I did for myself — was incredible,” son Joe Sanchez tells CBS 2’s Brad Edwards.
