An Idaho mother is facing a felony charge after police say she repeatedly handled her infant daughter with extreme force, allegedly shaking and jolting the child while insisting the baby was “not made of glass.”

Brenwyn Richey, 26, was arrested following a series of incidents in Blackfoot that led authorities to remove her newborn daughter from the home and launch a criminal investigation.

According to a probable cause affidavit, witnesses reported seeing Richey aggressively handle the infant on multiple occasions, including yanking the baby by her leg, bouncing her forcefully on her knee, and shaking her for extended periods.

One witness told police that when the child was just one week old, Richey dangled her by the leg without properly supporting her neck. When confronted, Richey allegedly responded that the baby was “not made of glass” and said “people do it all the time,” according to investigators.

Another witness described seeing Richey shake the infant in a repeated, forceful motion lasting between five and 15 minutes — or until the baby stopped crying.

Police first responded to Richey’s apartment on Dec. 28 after receiving a domestic disturbance call. During that encounter, Richey admitted to using excessive force while trying to care for the child.

According to the affidavit, she told officers she could be “aggressive with her baby sometimes,” specifically acknowledging that she would bounce the child on her leg with rapid, forceful motion and place her on a bed with excessive speed.

Officers noted that Richey demonstrated the behavior during the interview, describing it as a recurring issue she was “trying to work on.”

Authorities returned to the residence the following day, Dec. 29, prompting law enforcement to contact Child Protective Services. The agency, working with the Bonneville County Attorney’s Office, initiated an emergency removal of the infant from the home.

Officials also noted that a prior report existed involving THC exposure at the time of the child’s birth.

Medical evaluations soon raised further concern.

On Jan. 2, police were informed that an initial medical exam indicated possible internal injuries. Investigators noted the infant’s eyes appeared abnormally droopy for her developmental age.

A follow-up evaluation on Jan. 18 reportedly revealed persistent internal swelling of an undetermined cause.

Based on witness accounts, Richey’s own statements, and the medical findings, investigators concluded there was probable cause to charge her with felony injury to a child.

If convicted, Richey faces up to 10 years in prison.

She is scheduled to appear in court for a preliminary hearing on April 9.

The case remains under investigation.
