A Detroit woman was sentenced this month for making false bomb threats after her daughter was unable to appear in a high school play.
Crystal Royster, 42, called in a pair of false threats alleging there was a bomb at Lake Shore High School in St. Clair Shores, Michigan, about 17.6 miles northeast of Detroit, on March 12, 2025, the Macomb County Prosecutor’s Office said in a release on Thursday.
Royster made the threats after her daughter was sent home for being sick, thereby preventing her under school policy from appearing in the school play that day. Over 700 people were evacuated after the threats came in, and local police cleared the school and found no explosives.
Royster pleaded guilty to making a false report or threat of a bomb, a felony with a max sentence of four years in prison, on Nov. 13, 2025, the prosecutor’s office said.
Royster was sentenced on Jan. 8 to two weeks in prison, the first three days of which were credited for time served, and 18 months probation.
In addition, she is banned from contacting the victims, has to notify the school before she enters school grounds and has to take a “Class A impulse control class.”
“The defendant was sentenced today for making a false bomb report that resulted in a significant emergency response. While the court determined that probation was the appropriate outcome, her actions nonetheless caused disruption and concern within the community,” Macomb County Prosecutor Peter Lucido said Thursday.
