A family and church community called for justice Tuesday evening for a 2-month-old boy who died under disturbing circumstances last month.

At a vigil at Roseland Christian Ministries, at 109th Street and Michigan Avenue, those gathered expressed hope that the person who killed the baby boy, Kayson Flowers, would be held responsible.

Chicago police said Kayson was found unresponsive inside a home in the Roseland neighborhood, in the 200 block of West 106th Street, on Saturday, April 26. 

Kayson's mother said her son had just visited a close family member for a few days. Yet when the 2-month-old came back home, Kayla Flowers' only child was not breathing.

"Sorry, it's hard to talk about when my son when he's gone," said Kayla Flowers. "He should've been here with me."

Kayla Flowers stood with her pastor and family holding her up Tuesday evening at Roseland Christian Ministries. They were all seeking answers about Kayson's murder.

"Never got the chance to take his first step, never got the chance say his first words, never got the chance celebrate his first birthday," said Pastor Joe Huizenga of Roseland Christian Ministries.

Back in April, Kayson's mother said she let the child's father watch the boy for a few days. On the day Kason was to come home, a close family member brought the baby back in a stroller — insisting the boy was just sleeping.

"Me not thinking of it because it was raining, I just took my baby to the house — because I didn't want my child to get sick," said Kayla Flowers. "So when I went in the house, I uncovered the stroller and the car seat. My baby was lifeless."

The mother said she rushed her son to Roseland Community Hospital just minutes away, where doctors told her there was nothing they could do for her newborn. The Cook County Medical Examiner's office determined little Kayson had multiple injuries consistent with child abuse.

The family member who dropped off the child to the mother has not been seen since — leaving family heartbroken.

"Whoever knows something, please say something," said the victim's aunt, Meagan Flowers. "Kayson did not deserve this. Seeing him in that condition, lifeless, breaks our hearts every single day. Kayson was supposed to be here."

Roseland Christian Ministries first offered a $5,000 reward, and then someone added funds to bring the total reward to $7,500 as of Tuesday night. The pastor said someone on Kayson's dad's side of the family knows something, and believes the reward just may be enough to bring closure, or as they call it, "Justice for Kayson."

"What we're asking you tonight, whoever saw something, heard something, knows something — how much money do you need?" Huizenga said at the vigil. "What kind of reward do we need to raise for you to stop protecting somebody who would beat a baby to death?"

The family said they waited weeks, thinking Chicago police would find out who killed the baby. But they said after a month, it was time to speak out.

Chicago police said detectives are investigating the case, but have not named a person of interest as of yet.
