A Phelps County warrant issued for a Salem woman Friday alleges she attacked another woman in Rolla and beat her to the point she suffered a brain bleed and other injuries, according to documents filed in the 25th Judicial Circuit.

Mikayla Frey, 24, is charged with one felony count of first-degree assault resulting in serious physical injuries. Her bond was set at $250,000.

At 8:52 p.m. Tuesday an officer with the Rolla Police Department responded to the 1400 block of Martin Springs Drive on a report of an assault, according to the case’s probable cause report. Upon arrival, the report states a woman was found disoriented and covered in blood in a parking lot. She was subsequently sent to Phelps Health, where medical staff determined she had broken nose, fractured eye socket and brain bleed. The victim was then airlifted to University Medical Center in Columbia for additional treatment.

The report states the victim of the attack was unable to identify the attacker nor remember the night of the assault.

Police began investigating Frey after investigators were made aware she’d created a Facebook post prior to the attack on Tuesday in which she threatened to pull the victim out of a parked truck and beat her. Frey also posted a picture of what appeared to be her bruised knuckles on Tuesday after the attack occurred.

The report also cites a jail call conversation Frey engaged in with her incarcerated boyfriend after the attack in which she said she would likely be going to prison for violating her probation.
