MICHIGAN CITY, Ind. -- Two Michigan City parents are facing felony charges after an Indiana University Child Protection Program (IUCPPP) investigation determine the injuries to their infant were "inflicted injuries and not accidental trauma."

According to the La Porte County Sheriff's Office, deputies were dispatched to Franciscan Hospital on Feb. 3 in response to a seven-week-old female being treated by the emergency room for a broken femur and other injuries.

It was determined the infant needed advanced treatment and she was transported to Riley Children's Hospital later that same night.

According to Riley Children’s, the victim’s injuries include a left humerus fracture, lower left leg fractures of the tibia and fibula (metaphyseal lesions), subdural hematoma, posterior rib fractures, possible right humerus fracture, possible retroperitoneal hematoma, and abdominal bruising.

The baby girl was born on Dec. 15, 2024, and had been living with her biological parents, 26-yeaqr-old Kyle Hollihan and 23-year-old Kaitlyn Weissert, in Michigan City.

The victim is expected to make a full recovery but will "develop behind traditional stages of infant development."

"The victim was also determined to have a healing clavicle fracture that was indeterminate as to time, and it was concluded that said injury could have been a birthing injury," authorities said. "However, 'the remainder of her fractures are not consistent with birth injuries,' according to IUCPP’s final report [submitted] Feb. 28."

Riley Children’s also advised authorities that the injuries are inflicted injuries and not accidental trauma since they were all in different stages of healing, "making in reasonable to conclude that injuries to the victim were sustained on multiple dates."

The Nurse Practitioner assigned to treat the little girl at Riley said the lower left leg fractures to the tibia and fibula, called metaphyseal lesions, has a very aggressive mechanism as a cause.

That mechanism is a “violent twist of that area,” and the injury “is a fracture with a significant mechanism, especially for this age of child and how this occurs.”

"Evidence suggests victim’s amount of pain with some of her injuries caused extreme discomfort and pain, including the manipulation of her legs for bathing or dressing," authorities said. "[The] victim’s leg injury was such that the swelling discovered on Feb. 3 was likely caused by manipulation and aggravation to the existing fracture or injury."

Investigators say Hollihan and Weissert offered a variety of explanations for the child’s injuries, with each explanation being ruled out or deemed implausible.

Authorities say the victim was always with either of her parents or her maternal grandmother, who discovered swelling to the little girl's leg on Feb. 3, while she was caring for the child.

"She acted with persistence in urging Kaitlyn Weissert to take the child to urgent care because she feared the victim had significant medical issues," the LCSO said. 

"Hollihan and Weissert assert that Hollihan’s seven-year-old son, is the likely perpetrator of the victim’s injuries. Evidence has ruled out that potential cause. However, while tracking that and other potential causes, it became known that an alleged altercation occurred in the presence of that seven-year-old on Saturday, February 1, two days prior to the victim being taken to the hospital."

The LCSO says evidence suggests domestic violence may be present in the home despite Weissert stating otherwise.

"Additionally, the seven-year-old is seldom present with the victim, only visiting with Kyle Hollihan on Saturdays. Three Saturday visits may have taken place since the victim was born, and the son was eliminated as a suspect during the investigation," the LCSO said.

"Based on the evidence collected, the victim was injured on multiple dates, and both parents agree that they were with the victim each day since birth."

Hollihan is charged with Level 3 Felony Domestic Battery, Level 5 Felony Domestic Battery, Level 3 Felony Neglect of a Dependent (resulting in serious bodily injury), and Level 5 Felony Neglect of a Dependent (resulting in serious bodily injury).

Weissert is charged with Level 3 Felony Domestic Battery and Level 3 Felony Neglect of a Dependent (resulting in serious bodily injury).
