Surviving son of Dennis Deer, Chicago political family opens up after devastating loss

CHICAGO (WLS) -- Kanaan Deer is speaking publicly about the loss of his mother and twin brother and using his family's tragedy to raise awareness about mental health and the need for additional resources for people in crisis.

He lost his mother, Barbara Deer, and twin brother, Kaleb Deer, in April. Barbara Deer was killed by her son, who then took his own life. According to Kanaan, his brother had recently been diagnosed with a mental health disorder.

Barbara Deer was the wife of the late Cook County Commissioner and psychologist Dennis Deer.

"I was filled with fear. I was filled with confusion, a little bit of anger. It was the day when I got a call that my brother had killed my mom and right afterward he killed himself, which is something no family should have to go through," Kanaan Deer said.

Reflecting on the loss, Deer said, "It was very painful. It was very traumatic."

When asked whether he knew his brother was in crisis, Deer said, "It's hard to say with things like this."

"He was recently diagnosed with a mental health disorder," Deer said. "They have things called psychosis where they can't even control what's going on. They don't even know what's going on. I think it's important for him to not be defined by his final moments."

Despite the tragedy, Deer said he wants people to remember his brother for more than the circumstances of his death.

"He was my best friend, someone that countless nights we would think about how we could transform the community, transform the west side," Deer said.

Deer remembered his mother as a beloved figure in the community.

"My mom was the most beautiful soul that you could ever meet, imagine," he said.

"She was coined as the matriarch of the West Side... She was a mother for everyone."

Deer and his younger sister are expanding their family's nonprofit organization, Juneteenth Illinois, to provide additional mental health resources. He is also partnering with state Rep. La Shawn Ford on legislation and funding aimed at supporting families in crisis.

Ford praised Deer for sharing his story publicly.

"He's the perfect vehicle to let people know they can survive. We want to make sure he's able to continue the legacy his father, mother and brother gave," Ford said.

Deer said he chose to speak publicly because he hopes it will help others facing difficult circumstances.

"There's someone out there somewhere that may be going through a divorce, a heartbreak, a bad day at work, something significant enough that they're contemplating doing something that they shouldn't do," he said.

"It's my job or my mission from God that those resources are in place."

Deer said the day after his interview would have been his late father's birthday. He said he wants to make his father, mother and brother proud while continuing to remind people facing a crisis that they are not alone and to advocate for more mental health resources.
