The two teenage girls who were killed were sitting behind the counter in the mobile shop along with a third teenage girl, Jamie Smith. There was several people in the shop at the time and the girls were talking among themselves. A van pulled up outside the shop and a masked gunman wearing military style clothing, armed with a 9mm Browning pistol, jumped out. One of the people in the shop presuming it was Republicans yelled "Provisional IRA, hit the floor!". Most people managed to escape, but the three girls were stuck and trapped behind the counter. The gunman pulled Jamie Smith by the hair calling her a "Fenian slut" and then threw her out of the shop. The UVF gunman then shot Duffy and Rennie, killing them both. While the attack was taking place, Brian Frizzell walked into the shop, and was shot as the gunman was leaving the store. Eileen's brother Brendan Duffy was one of the first at the shop after the attack, he described the scene: "Brian Frizzell was lying in a pool of blood. Katrina was still sitting on the crate. She was dead but her blue eyes were wide open and there was a bullet wound on her neck. Eileen was slumped on the floor, shot in the head. Her face was badly swollen and blood was pumping out of her head and ears. I tried to resuscitate her but in my heart I knew she was gone. I was so numb, I couldn't cry."
Aftermath
The killings drew widespread condemnation from both the Catholic and Protestant communities in Northern Ireland. The funerals were attended by thousands of people. It's believed Billy Wrights right hand man & second in command of the UVF unit at the time, who carried out the Drumbeg murders. The killer was seen with Billy Wright at a number of rallies & marchers at Portadown. It's believed the killings of Protestant civilians Derek Patterson on the 9 April & Ian Sproule on the 12 April were in retaliation to the Drumbeg killings. Eight months after the attack three more civilians were killed by the UVF in the Craigavon area at the Carbet Road-Carn Road junction. Desmond Rogers, Fergus Magee, and John Lavery were shot dead, Rogers and Magee were Catholics, Lavery a Protestant. The three men were shot in their car after being stopped at an illegal UVF checkpoint. The UVF later apologized for killing the Protestant man. In October 1992, a man, Vicky Ahitty, from Portadown, was charged with these and other murders and firearms possession. In 1992, Tom Harper was charged with the Drumbeg mobile shop murders, although he was the driver and not the gunman. He was given a life sentence for his part in the murders. The attack was ordered by Billy Wright, but the gunman has never been charged. Local allegations of security force collusion remain and it was noted that, on the night of the shooting, the normally heavy police presence was not apparent. In September 2011, the PSNI announced that records of interviews with suspects in key murder investigations from 1985 to 1993 had been destroyed in 1998 as the place they were stored was contaminated with asbestos. They included the records in this case.
