A Chicago man with disabilities was shot while waiting for a bus to school Wednesday morning.

Philip Rega and his sons were at the bus stop in front of their home when three people approached and started yelling gang slogans, according to the Chicago Sun-Times. He was about to call 911 when shots rang out – nearly 40 rounds by police count.

His older son, 21-year-old Jesus Rega, was hit three times, including once in the head, police said. The father and his other son who is 15 years old were not hurt.

Jesus was taken to a hospital in critical condition, where he underwent surgery.

"Right now he’s alive and well, thank God," Philip told the newspaper. "But he’s still not out of the woods. He’s gonna be in the hospital for at least a few more weeks."

Chicago police said during a news conference the shooting happened around 6:38 a.m. in the 4700 block of South Wolcott.

"Because they shouted out gang slogans [we believe] that’s an effort to identify if the victims in this case were in fact gang members themselves, which they were not," Chicago Police Cmdr. Don Jerome said.

Still, the gang members opened fire. Some of the bullets even reportedly hit homes along the block The suspects ran north, and no arrests have been made.

"It’s terribly brazen," Philip said. "No one should be shot, let alone shot while standing [and] waiting for a school bus. No father should see his children shot like this."

Police believe the attack on the Regas is also related to another shooting that happened a few hours later nearby, although no one was injured in that incident.
