CHICAGO (CBS) — Police on Thursday were asking for help from the public in identifying two suspects in a shooting that killed a 14-year-old boy in Roseland this past weekend.

The boy’s mother was shot and killed on the very same block days later.

As CBS 2’s Steven Graves reported Thursday night, Area Two detectives are not ready to give out the specific location where the new surveillance video was shot – or if the suspects are also connected to the mom’s murder.

But they hope someone will recognize the young men whom they call killers.

At 5:09 p.m. Sunday, Kevin Tinker Jr., 14, was shot and killed in the 200 block of West 110th Place, off Wentworth Avenue.

The 14-year-old was shot multiple times.

Early Wednesday morning, Kevin’s mother – Delisa Tucker, 31, – was also shot in the chest and killed while visiting the spot where her son was killed. Tucker was a mother of six.

“We need justice for Delisa and Kevin,” family friend Michelle Tharpe told CBS 2’s Suzanne Le Mignot earlier this week. “That’s all we want.”

Tinker’s father, Kevin Tinker Sr., said his son was walking home from a friend’s house when he was shot.

“Some violence found him,” said Tinker Sr. “He was a good kid. He didn’t gang bang. Played basketball. Played on his phone a lot. He liked to play games. He was not a gangbanger at all. He stayed in the house most of the time, with his little brothers and sisters.”

Again, Area Two detectives late Thursday were only connecting the suspects to Kevin’s murder.

Both are wearing black hooded sweat shirts and black pants, and one is wearing black gym shoes, the other white gym shoes.

They’re seen on surveillance video at the unidentified store, buying something with cash and later checking out.

Soon after, video picks them up getting into a silver Nissan with an Illinois license plate in pain view. The two sit in the vehicle for a bit, fidgeting with something that one suspect throws out the window – which might have fingerprints on it.

Detectives are hoping this can bring some type of closure for a family, as they continuing to raise money for two funerals.

Family members late Thursday told CBS 2’s Graves they did not recognize the people in the video.

Tucker leaves behind five children between the ages of 4 and 15. Her loved ones have set up a GoFundMe page for help with funeral expenses and to provide for her children.
