A Bartow man is behind bars after beating his 4-month-old daughter to death, according to the Polk County Sheriff's Office. It happened the evening of Feb. 22, Sheriff Grady Judd and Police Chief Andy Ray said during a joint news conference Wednesday afternoon. "I want to introduce you to a murderer, to someone who viciously murdered his beautiful 4 [month] old baby girl..." Judd said while holding a photo of 22-year-old Jacob Kubai. Kubai reportedly took his wife to work around 5 p.m. before returning home for the night with their daughter Willow, whose nickname is "Strawberry." According to the sheriff, Kubai told detectives that while making dinner that night, he realized he didn't have chicken broth and drove to Walmart with his daughter. "We pulled the video at Walmart and he has no baby," Judd said. Kubai told detectives he returned home, fed the baby and continued checking on her every 10 minutes. During his 8:10 p.m. check, Kubai said Willow was unresponsive. He told detectives he performed CPR on his daughter and drove her to Bartow Regional Medical Center.
