NASHVILLE, Tenn. (WSMV) - A man who said he was at Mill Creek Greenway Monday afternoon shared what he saw and heard when an innocent woman was shot and killed.

Police arrested 29-year-old Paul Park of Brentwood and charged him with criminal homicide. Park is accused of fatally shooting 34-year-old Alyssa Lokits.

A man, who did not want to share his name, said he was at the park to see the fall foliage when he heard someone screaming.

“I heard a scream, but it wasn’t clear it sounded like it could have been something else and then a few minutes later, I heard a second scream,” the man said.

During that second scream, he heard a woman crying out for help. “She said, ‘Help, I’m being raped, I’m being raped,’ and then the shots were instantaneous,” the man said.

After hearing those bone-chilling words, the man said the sound of at least five gunshots rang out. He then started running towards the screams.

“It didn’t take long to find her and when we did, she was shot in the head,” the man said. “Just panic and trying to help to the extent that I could and I called 9-1-1 and was trying to get an ambulance there and get authorities there as fast as I could,” the man said.

Multiple Metro Nashville Police Department officers rushed to the scene.

“We believe that Alyssa was apparently exercising on the greenway when a man abdicated her into an overgrown area and attempted to sexually assault her and then shot her,” Metro Nashville Police Chief John Drake said.

During a news conference Tuesday afternoon, Chief Drake said 34-year-old Alyssa Lokits died Monday night after being rushed to Vanderbilt University Medical Center with multiple injuries. Lokits has been identified as a Vanderbilt University graduate.

When the man heard the woman had died he said he was heartbroken.

“I’m so sorry that this happened to her,” he said.

The man said he had a dash camera that had been recording and shared that video with police Monday night. Officers said that the very next day detectives used dash camera video to identify, track down, and arrest 29-year-old Paul Park. They said the video caught him committing the crime.

“It’s terrifying, it’s unsettling, all of it is just unfair for the poor woman who lost her life,” the man said.

Park is scheduled to appear in Davidson County court on Thursday.
