A 52-year-old woman beat up her 87-year-old boyfriend of 37 years because she thought he cheated, prosecutors said in a Miami-Dade bond court.

Regina Soivilien, 52, is facing a felony charge of battery on a person over the age of 65, which is punishable by up to five years in prison.

“They’ve been together for 37 years," the prosecutor said. "He’s cheating on you at 87? Gee whiz.”

Soivilien's public defender asked the court for a non-monetary bond, called Pretrial Services in Miami-Dade, to secure her release because she does not have a criminal record.

Judge Mindy S. Glazer said Soivilien must stay at least 500 feet away from her boyfriend, as well as his home, school and workplace, or she faces the risk of violating her bond and being detained. She would also have to pay $5,000 if she violates the conditions under the Pretrial Services.

Soivilien said she will stay with her sister in the meantime while her boyfriend, who sustained bumps and bruises on his face when she allegedly punched him several times, recovers.
