LEONARDTOWN, MD (March 31, 2025) – State’s Attorney Jaymi Sterling announced today that a St. Mary’s County jury found Robert Humphries, III, 29, of Waldorf, Maryland, guilty of felony robbery, felony third-degree burglary, second-degree assault, theft, and multiple counts of malicious destruction of property, stemming from a domestic violence incident.

On August 9, 2024, deputies from the St. Mary’s County Sheriff’s Office responded to a residence in Lexington Park and discovered that Humphries had broken through the victim’s front door, assaulted her, stole her property, then fled the scene. The crimes were committed in the presence of the victim’s child.

The next day, Humphries returned to the victim’s apartment, forcefully robbed her of her phone, and broke one of her apartment windows.

After a two-day jury trial, a St. Mary’s County jury convicted Humphries and determined that he committed the crimes of violence in the presence of a minor. This finding provides prosecutors with the ability to advocate for an additional five years of incarceration at sentencing.

“The Defendant terrorized the victim over a period of two days and robbed her in her own home,” said State’s Attorney Jaymi Sterling. “Our office will continue to vigorously prosecute domestic violence offenders and advocate for domestic violence survivors.”

After the jury’s verdict, the Court granted the State’s request to revoke Humphries’s bond pending a sentencing hearing. The maximum sentence is 40 years and 210 days in prison.

Senior Assistant State’s Attorney Donna Pettersen, Chief of the Domestic Violence Unit, prosecuted the case on behalf of the citizens of St. Mary’s County.

Deputies Tyler Nichols and Mina Geric of the St. Mary’s County Sheriff’s Office were the lead investigators.

The Honorable Amy Lorenzini presided over the case.
