A University of Iowa graduate student was on her way to a family gathering last weekend when her brother accidentally shot and killed her while demonstrating how to clean a handgun.

The Sac County Sheriff’s Office said in a news release Wednesday that 24-year-old Megan Quinn Sloss, of Guthrie Center, was driving Sunday with her 26-year-old brother, Spencer Lee Sloss, when she was shot.

Investigators say Megan was in the driver’s seat and her brother was in the front passenger seat at the time of the incident, which took place at around 11.40am Sunday near Lake View, Iowa.

The Sloss siblings were on their way to a family event in Ida County, and later they were planning to do some target shooting.

Spencer Sloss was showing his younger sister how to disassemble his Sig Sauer 9mm handgun to clean it when it discharged, striking her in the hip.

Her brother had to climb over the arm rest to stop the car after his sister was shot, and he then called 911 for help and carried Megan out of the car.

A doctor driving by stopped to render medical aid until Sloss was taken to Loring Hospital in Sac City. She was then flown to Mercy Medical in Des Moines, where she died from her injury.

Officials say Spencer Sloss has a valid permit to carry the handgun. No charges have been brought against him, and the shooting remains under investigation.

According to her obituary, Megan Sloss was pursuing a Master's degree in social services and planned to spend her career helping children and adults in need.

'Saddened to lose Hawkeye Megan Sloss, a grad student looking to help others in need,' the University of Iowa tweeted Tuesday, reported the Iowa City Press-Citizen.

Sloss was also working at Iowa KidSight and the University of Iowa Hospitals and Clinics.

'She was the homecoming queen, a beautiful dancer, a teacher, a good friend to many and a lover of the little things in life,' the obituary reads. 'She had an uncommon devotion to God and her Church. She had a beautiful and kind spirit that touched many lives.'
