(STMW) — A young mother admitted she brutally stabbed her 5-month-old son because she had premonitions something bad would happen to him and was afraid authorities would take the infant away because of her crack habit, Cook County prosecutors said Friday.

The only regret Kimberlynn Bolanos told authorities she had after stabbing the boy nearly 30 times was that she “wasn’t sure if her baby was dead and that she would feel better if he was dead,” Assistant State’s Attorney Bridget O’Brien said.

Isaac Bolanos was killed in the May 30 attack in a North Side motel bathroom, prosecutors said.

He was stabbed 21 times in the head, eight times in the chest and had his throat slit from “ear to ear” while strapped in his car seat, O’Brien said.

Two days before, Bolanos checked into the Diplomat Hotel with her baby and invited her boyfriend to spend the night, O’Brien said.

When the boyfriend left the motel the next morning, Bolanos, 21, took her baby and walked to a nearby Dollar Tree store where she allegedly purchased knives and a pack of razors, the Chicago Sun-Times is reporting.

The boyfriend returned to the motel, in the 5200 block of North Lincoln Avenue, later that night and slept over after he and Bolanos smoked some marijuana and drank some Bacardi rum, O’Brien said.

When the boyfriend woke up in the morning, he noticed the knives and blades next to a sleeping Bolanos and moved them to the dresser, O’Brien said.

After Bolanos woke up, she went to take a shower, allegedly taking Isaac in the bathroom with her.

The boyfriend knocked on the door a half-hour later and asked if everything was OK.

He then tried opening the door, but Bolanos pushed back, O’Brien said.

The boyfriend was able to peer through the door and saw a blood-soaked Isaac with a gash on his head, O’Brien said.

The boyfriend called 911 and when authorities arrived, they had to use an ax to break down the door of the bathroom where they found the dead baby and Bolanos who apparently tried killing herself, authorities said.

Bolanos, of the 2700 block of West Balmoral, suffers from mental disorders, Assistant Public Defender Marijane Placek said.

When she was on her medication, Bolanos held various jobs, including one at the Chicago Park District, Placek said.

Judge Adam Bourgeois Jr. ordered Bolanos held without bail.

He also said she will be housed at the Cook County Jail’s Cermak Hospital.

Bolanos’ relatives refused comment following Friday’s hearing.
