Police said Wade Edwards, 41, shot Harp four times below the belt after he came home to find him having sex with his teenage stepdaughter. Harp said within 10 seconds of being caught all he could hear was the father cocking his gun.
"As soon as I take a couple of steps down the stairs, he's shooting me," Harp said. "When he shot me the second time I took off running down the stairs."
Harp said he was hit with another bullet as he was running out of the house.
"When I take off running, that's when he shoots me in my rump," Harp said.
Harp said he screamed for help before he collapsed on the sidewalk in front of a neighbor who called 911.
"I can't tell if he's got his clothes on, his leg is covered in blood," a neighbor said.
"I was just lying there, I couldn't do nothing. My whole body was getting stiff, turning purple," Harp recalled.
Within minutes Harp was rushed to a hospital. Surgeons removed bullets from Harp's body. He is now recovering from his injuries.

An Apopka man who shot his stepdaughter's boyfriend got immunity from prosecution. The defense argued Wednesday afternoon, that Wade Edwards should never have been charged for shooting the young man after he caught him having sex with his stepdaughter.
WFTV reporter Melonie Holt was in court Wednesday when both Edwards and his stepdaughter testified. According to prosecutors, Edwards acted out of anger. But the Apopka dad has maintained that he acted in defense of his home.
After court, Edwards told WFTV he was glad it is over.
Wednesday afternoon, 41-year-old Wade Edwards took the stand to avoid a trial. The Apopka father was charged with second-degree attempted murder, attempted manslaughter and aggravated battery for shooting his 16-year-old stepdaughter's love interest.
In October of 2009, Edwards heard a noise, entered his stepdaughter’s bedroom and witnessed what he thought was an assault. He returned with a gun.
“I was trying to defend my daughter and my home,” Edwards told WFTV.
Edwards testified that when he shot Julian Harp, he had no idea the teen had been invited by his daughter.
“I thought it looked like something was going on like having sex, my daughter getting raped or killed or something like that,” he said.
Edwards interrupted a lover's tryst. According to investigators, Julian Harp was hit in the lower back, buttocks and twice in his left leg.
Edward's stepdaughter took the stand in her stepdad's defense.
“Was the only look you saw on his face fear?” stepdaughter Shaquan Galloway was asked in court.
“Yes,” she answered.
“The victim was leaving as Mr. Edwards started shooting. So, it's not the fact that he shot the man in his house, it's why he shot him,” Assistant State Attorney Nicole Pegues said.
Edwards admitted to struggling with the shooting.
"Have you never shot anybody before?" Defense Attorney Peter Zies said.
"I never had to shoot anybody before this," Edwards replied.
"Was it something that upset you a great deal having to do what happened?” Zies asked.
"Still does," he answered.
Late Wednesday afternoon, Judge Tim Shea sided with Edwards effectively ending the prosecution.
