Teen charged in violent Montgomery County robbery and assault spree
Gaithersburg, MD — An 18-year-old from Saint Leonard is being held without bond after detectives linked him to a string of armed robberies, assaults, and thefts across Montgomery County spanning late 2023 into mid-2024, police announced Friday.
The Montgomery County Department of Police Major Crimes Division charged Joseph Tyler Jhingory IV with home invasion, armed robbery, false imprisonment, sexual assault, assault, vehicle theft, and related offenses.
Investigators said the crime spree began on December 1, 2023, when Jhingory allegedly broke into a Rockville home with a gun, tied up the residents, sexually assaulted a female victim, and fled in the family’s Volvo CX-40.
On February 8, 2024, two Bethesda homes were burglarized and a 2015 Mercedes GLK350 stolen. Just hours later, a gas station on Wisconsin Avenue was robbed, with the attendant tied up and cash and merchandise stolen. Days afterward, police say Jhingory attempted burglaries in Anne Arundel County before crashing the stolen Mercedes during a pursuit.
On February 17, he allegedly tried to rob a man outside a 7-Eleven, then fled onto Andrews Air Force Base, where he stole a car, crashed, and was arrested by military police. He was released shortly after.
The investigation also tied him to a July 10, 2024, burglary in Potomac, where personal items and a 2014 Lexus were stolen. That vehicle was later recovered in Calvert County, where several other stolen cars had been abandoned.
Detectives eventually connected the crimes through evidence and served Jhingory with warrants on August 27, 2025, after he was transferred from a juvenile facility on unrelated charges.
He remains held without bond as the cases proceed.
