Alabama authorities said they found the body of a woman buried in the backyard of a house in Hueytown, about 13 miles west of Birmingham.

Lynneice Washington, district attorney for the Bessemer Cutoff District of Jefferson County, told news outlets that the woman’s body was found in a shallow grave at the home. The woman has not been identified.

Law enforcement searched the home after receiving tips, she said. There had been a heavy police presence at the home for two days with multiple law enforcement agencies participating.

The Jefferson County Sheriff’s Office is taking the lead in the investigation, Chief Deputy David Agee told reporters.

“Right now, we have a lot more questions than answers, but we hope to have those answers soon,” Agee said.

Washington said it is always difficult when human remains are found.

“It’s always hard whenever you find remains of a person because there are family members…The only thing we can do at this point is to try to give them justice,” Washington said.

Authorities have not announced if the investigation is connected to the case of a missing woman. Paighton Houston, 29, was last seen Dec. 20 leaving a Birmingham bar.

Family members told news outlets that she later sent a text to a friend saying she didn’t know who she was with and felt in trouble.
