CHICAGO (CBS) — Nine people were killed, and 30 more were wounded in shootings across the city over the weekend.

Police said 20 of the shootings over the weekend were gang-related, and the victims included high-ranking gang members.

The ongoing gun violence in Chicago has been a concern for people in the community.

Several community organizations and faith-based groups met Monday morning at Chicago Public Safety Headquarters for training on ways they can help increase safety and reduce crime through the program Force For Good.

Police will work with the groups for 12 months on how to effectively work together, and grow and build partnerships between residents and the department.

The most recent fatal shooting happened shortly after 5 p.m. Sunday in the Back of the Yards neighborhood. Police said man was sitting on a porch near 54th and Winchester, when a gunman walked through the gangway and began shooting.

The victim was shot once in the chest and three times in the back, and was pronounced dead at the hospital at 5:35 p.m. The Cook County Medical Examiner’s office identified the victim as 26-year-old Gregory Jodie.

Around 3:20 a.m. Sunday, a man was walking near 59th and Halsted in the Englewood neighborhood, when a green vehicle drove past, and someone shot him several times in the chest, stomach, back, and arms. The victim, 24-year-old Cornelius Bell, was taken to the University of Chicago trauma center, where he was pronounced dead at 4:01 a.m.

At about 1:15 a.m. Sunday, a man was sitting in his car near Garfield and Winchester, when someone walked up and shot him in the abdomen.

The victim, 29-year-old Devane Walker, was able to drive his car a short distance before hitting a parked car. He was taken to the University of Chicago trauma center, where he was pronounced dead at 4:46 a.m.

Around 1:10 a.m. Sunday, six people were gathered outside near 64th and Eberhart in the West Woodlawn neighborhood, when someone began shooting, possibly from a passing car. One victim, 39-year-old Tyrone White, was pronounced dead at the University of Chicago trauma center at 1:37 a.m.

Five other people were wounded in the attack, including a 19-year-old man who was shot in the back, a 21-year-old man who was grazed in the head, a 24-year-old woman who was shot in the arm, a 21-year-old man who was shot in the leg, and a 24-year-old man who was shot in the leg.

Police Supt. Eddie Johnson said two of the victims are members of the same gang, and all six have extensive histories with the police department.

“We saw a higher victim count in that incident as the exchange turned into a gun battle between our offenders and victims,” Johnson said.

The superintendent said, while detectives have identified the likely conflict that prompted the shooting, and were processing ballistics evidence from several different firearms, he said, “We are not getting cooperation from any of our non-fatal victims.”

Around 8:20 p.m. Saturday, a 40-year-old man was in the 7600 block of South Rhodes in the Chatham neighborhood when a gunman got out of a dark-colored vehicle and opened fire. The victim was taken to the University of Chicago trauma center, where he was pronounced dead.
