She is used to hearing gunshots near her St. Helena Island home.
But just after midnight Thursday, the grandmother heard a volley like none she had heard before.
The first burst was four shots.
Then came six more.
New bursts came every hour or so.
"It was one after the other," she said of the shots that came in bursts throughout the morning. "Bam! Bam! Bam!"
The woman, who spoke on condition that her name not be published, had never called authorities about the shots. She was not always sure she knew what she was hearing. She thought some might be firecrackers. At other times, the sounds echoed from far enough away that she still felt safe in her home near Capers Creek.
But the shots she heard early Thursday sounded as if they were coming from her front yard.
She called 911 at 1:02 a.m., according to a Beaufort County Sheriff's Office report, and deputies responded 22 minutes later.
While surveying the area, deputies heard five shots fired from an undetermined location, the report said.
Deputies were unable to determine where the shots were coming from or who was responsible. They searched for shell casings, gunshot victims and property damage.
They found nothing.
Before leaving, a deputy asked the grandmother for her name. This is when she became nervous.
"I told them I don't want my name to go into anything," she said. "I don't know who's (shooting), and they could come after me."
Sheriff P.J. Tanner said reports of shots fired are not uncommon in unincorporated Beaufort County, and are often dead ends for deputies.
"By the time it's called in and dispatched and the deputy gets there, you could have anywhere from six, seven, eight, 10 minutes pass," Tanner said. "If the person's gone, it's really hard to identify the person responsible for firing, what they were shooting at and why."
A neighbor down the road, who also asked to remain anonymous, said she also heard shots Thursday morning, but said gunfire is a rare occurrence.
At least until recently.
Thursday's incident marked the second time in as many months she's heard multiple rounds of shots in the middle of the night. During the previous episode, the neighbor called 911 at 2 a.m. but doesn't know if deputies responded.
"It was early in the morning and I was hearing gunshots. I wasn't going to go outside," she said.
The neighbor said she tries not to leave her home when it's dark because nighttime crime is common in the area. On April 24, she reported that her car was vandalized overnight. The door frame was damaged where it appeared someone tried to remove the lock.
"The officer said they were going to beef up patrol in the area, and I have been seeing more (deputies in the area) than normal," she said.
A resident on an adjacent street, who also requested anonymity, said she heard the shots fired Thursday morning as well. She occasionally hears shots during the night, but said it's "not every night and not every week."
"In this area, there's some children, and some older, grown folks," she said. "No teenagers really, so I don't know what that is all about."
Just before 3 a.m. Thursday, the grandmother called 911 again. She handed the phone to her son-in-law, who reported hearing five shots that were fired across the street.
Deputies responded, checking the area again for shell casings, a gunshot victim or property damage, and again found nothing, according to a Beaufort County Sheriff's Office report.
Deputies heard five more shots ring out as they were leaving, the report said.
They surveyed the area.
There was nothing.
