NORTH FORSYTH — A north Forsyth teenager injured in a crash that claimed the life of his grandfather has succumbed to his injuries.

Joseph Jude “Joe” Dumphy, 15, died Sunday after sustaining life-threatening injuries during a two-vehicle crash June 27 in front of Chestatee subdivision on Ga. 400.

“We received confirmation from [Dawson County] Coroner Ted Bearden that he did pass away this morning,” said Robin Stone, a spokeswoman for the Georgia State Patrol.

Dumphy’s grandfather, John Joseph Dumphy, 78, died at the scene of the collision. His wife was also injured in the wreck.

According to his obituary, the younger Dumphy had lived in Forsyth County for 11 years. He was a rising sophomore at North Forsyth High School, where he was a member of the varsity golf team and Fellowship of Christian Athletes. He also was a member of Chestatee Golf Club and played on the Hurricane Junior Golf Tour.

According to his obituary, he made an impact on the lives of others with the donation of five of his organs to those in need.

According to the state patrol, the fatal crash occurred last month when the elder Dumphy failed to yield the right of way to a northbound Jeep driven by a Dahlonega man.

“Witnesses stated that [Dumphy] stopped at the stop sign, but then slowly drove across [Ga.] 400, where his car was struck by the Jeep,” Stone said.

An 18-year-old passenger in the Jeep also was injured in the crash when the vehicle overturned on impact.

According to the state patrol, with exception of the elder Dumphy, everyone in both vehicles was wearing seatbelts.

Drugs and alcohol are not considered factors in the collision. No charges will be filed, according to the state patrol, as the driver at fault was killed.

In addition to his grandmother, Joe Dumphy’s immediate survivors include his parents, a sister and three other grandparents.

Funeral services are scheduled for 11 a.m. Friday at Good Shepherd Catholic Church.

In lieu of flowers, donations may be made to “The Joe Dumphy Memorial Golf Scholarship”, c/o Moore Wealth Management, 210 Washington St., N.W., Suite 106, Gainesville, GA  30501.
