Martinson to stand trial Monday for 10 counts aggravated child abuse

Tyler Bryan Martinson, 29, was found guilty of six counts of felony aggravated child abuse

GILLETTE, Wyo.— Nearly two-thirds of the charges filed against a Gillette man accused of violently abusing his infant son have been dismissed ahead of a seven-day trial beginning Monday, Campbell County court records show.

Tyler Bryan Martinson, 29, will now stand trial on May 2 for 10 counts of felony aggravated child abuse following a filing from the state dismissing 21 counts of the same on April 21, court records indicate.

The charges against Martinson stem from multiple incidents that occurred between 2020 and 2021 where prosecutors believe he violently abused his then 3-month-old son and broke 31 of the child’s bones, according to an affidavit of probable cause filed in the case.

The baby’s injuries were brought to light in January 2021 after he was taken to the emergency room at Campbell County Health (CCH) in January 2021 by his mother, Keasha Bullinger, and Martinson because the child was having difficulty using his right leg and his ribs were making a popping sound every time he took a breath, per the affidavit.

Martinson told CCH staff “I might have been a little rough” and Bullinger said “Well, he was doing cycling to get gas out,” the affidavit states.

Multiple fractures were identified on the baby’s ribs as well as two breaks along his femur which doctors said came from “high-speed, brute force trauma” and that the force necessary to inflict the injuries was akin to a violent car crash, according to the affidavit.

Doctors ultimately diagnosed the injuries as child abuse and notified the police while the baby was transported to the Children’s Hospital Colorado in Denver, Colorado, where medical staff reported he suffered a total of 31 broken bones, per the affidavit.

The night prior to the emergency room visit Martinson had been alone with the baby for several hours while Bullinger was at work. When she returned, the baby was screaming while Martinson was trying to feed him.

When interviewed by the police, Bullinger said that she believed her baby was fake crying and whimpering at the time, which is when Martinson allegedly voiced concerns over the child’s swollen right leg and they later took him to the hospital after the baby began screaming, per the affidavit.

During his interview with police detectives, Martinson allegedly stated “I got angry, you know, I just have a lot going on and I just lost it. I guess,” the affidavit states.

Bullinger told detectives that she saw Martinson being too rough with the child several times and had spoken with him twice about him hurting the baby, per the affidavit, which states Martinson left thumbprint-sized bruises on the baby whenever he picked him up and that the baby would start to cry whenever Martinson walked into the room.

On one occasion, Bullinger recalled walking into a room to find that the baby had defecated on Martinson while he was changing his son’s diaper and the baby was making a gurgling sound from blood in his mouth.

Martinson was taken into custody on Jan. 4, 2021, for aggravated child abuse and was released after posting a $100,000 bond.

He has maintained a not-guilty plea for all charges brought against him.
