HALLANDALE BEACH, Fla. — A Hallandale Beach man is facing a manslaughter charge after he killed his baby son through severe abuse, authorities said in court documents obtained by Local 10 News on Tuesday.
Robert Lee Boesenberg, 30, was arrested on Friday, more than three years after authorities said he brought an unresponsive 6-month-old Lincoln Boesenberg to Joe DiMaggio Children’s Hospital in Hollywood on New Year’s Day 2022. Investigators said an initial examination showed that Lincoln’s injuries, characterized as “abusive head trauma,” were “likely caused by violent shaking.”
Boesenberg had only been awarded full custody of Lincoln 10 days prior, police said.
Two weeks after arriving at JDCH, Lincoln, who had been “otherwise healthy” leading up to the incident, would die of “craniocerebral blunt trauma,” an investigator with the Hallandale Beach Police Department said in an arrest affidavit. His injuries included a skull fracture and a brain bleed and his cause of death was ruled a homicide.
According to the complaint, Boesenberg and the child’s mother, whose name was redacted, had been awarded full custody of Lincoln and their 1-year-old daughter on Dec. 22, 2021.
Before then, police said the children had been living with a foster parent due to Boesenberg and the children’s mother having a “substance abuse history and a prior neglect case” with the Florida Department of Children and Families.
Lincoln had been removed from their care at birth because both parents continued to test positive, according to the arrest affidavit, which contains multiple redacted sections.
Eventually, after routine drug testing, Boesenberg and the children’s mother were granted supervised visits and eventually unsupervised and overnight visits before regaining custody.
Police said more than three years after Lincoln’s death, the Broward Medical Examiner’s Office issued a final autopsy report on Sept. 5, a week before Hallandale Beach police took Boesenberg into custody.
As of Tuesday, Boesenberg was being held without bond in the Broward Main Jail on charges of aggravated manslaughter of a child and aggravated child abuse.
