The Medical Examiner’s Office has determined the death of 90 Day Fiancé star Leida Margaretha’s five-week-old daughter Alisa Eleanor Rosenbrook in July of last year was “non-accidental.”

The Initial Assessment completed by the Adams County Health and Human Services Department “found a preponderance of the evidence to substantiate maltreatment of physical abuse to the infant by the mother.”

The agency stated that “no criminal charges have been filed in this case, and the investigation remains open.”

The information is included in multiple reports filed with Wisconsin’s Department of Children and Families Division of Safety and Permanence. The first is the 90-Day Summary Report for Child Death, Serious Injury or Egregious Incident. The same information is repeated in the 6-Month Final Summary Report.

LEIDA MARGARETHA’S DAUGHTER’S DEATH

Leida Margaretha’s husband Eric Rosenbrook was booked for domestic battery and domestic disorderly conduct just before 3AM on Saturday, July 5, 2025. Leida stated in a video that Eric had been drinking and he slapped her after she refused to let him hold their daughter.

Much later on July 5, Leida’s daughter Alisa was found unresponsive. Eric was still in jail at the time.

Below is a recap of the events from a statement issued by Adams County Sheriff Brent York:

On Saturday, July 5, 2025 the Adams County Sheriff’s Office received a 911 call from a residence in the City of Adams, Adams County, Wisconsin reporting an unresponsive five-week-old infant.

The City of Adams Police Department responded to the scene, along with LifeStar Ambulance Service. LifeStar Ambulance Service transported the infant to Gunderson Moundview Hospital. The infant was then transported to UW Health American Family Children’s Hospital in Madison.

On July 6, 2025, the City of Adams Police Department requested that the Sheriff’s Office take over the case.

On July 9, 2025, the child died at UW Health American Family Children’s Hospital. Any time an infant death occurs in Adams County a formal investigation takes place.

This is an active investigation and as such, no further information will be released at this time.

During the time that Alisa was in the hospital, Leida posted numerous videos on Instagram. She talked about going through a hard time, but didn’t share any details.

Multiple alleged text and voice messages between Leida and a blogger later surfaced in which she gave differing accounts of what happened to Alisa. In none of the exchanges did she seem overly emotional or distraught.

Alleged text messages between Eric Rosenbrook and a blogger claim that Leida took her son Alessandro to Indonesia some time around July 15.

“[Leida] did leave the country last week,” one alleged text from Eric reads. “Took her son home and left him with her parents. Then returned.” This claim seems confirmed by the reports because they state Alessandro is “safe with relatives.”
