Authorities are searching for the killer of a woman and her dog, both found dead at a popular park in Atlanta, Georgia last Wednesday.
Around 1 a.m., Katherine Janness, 40, and her dog, Bowie, were found by her wife Emma Clark, police told TV station WSB-TV.
After Janness never came home from walking the dog, Clark tracked Janness's phone to where the bodies were.
Janness had been stabbed several times. The local news reported she had been disfigured.
Deputy Police Chief Charles Hampton said it was a "gruesome scene."
The FBI has joined the case, according to ABC News. No arrests have been made.
Authorities shared an image of Janness near the park walking her dog as they search for those responsible. They've also put up a $10,000 reward for information about the killing.
Atlanta has seen about 80 homicides since the beginning of the year, according to The Atlanta-Journal Constitution.
More than 100 people gathered in Janness's memory at a candlelight vigil held on Thursday night.
"What they did to her is ridiculous. There is a monster on the loose in the city of Atlanta," Joe Clark, Janness's father-in-law, told WSB-TV.
"Katie can't be seen. You can't look at her because of what they did to her. What they've done is put the knife in my daughter's heart at the same time," Clark said.
In a Go Fund Me page for funeral expenses, Clark wrote, "[Janness] was the most intelligent, kind, humble, and beautiful person I have ever known. I wanted to spend every second with her."
She added that Bowie, their dog, was a great companion.
"My heart is so very broken, my world will never be the same."
