Five people have been killed in an Alabama home in what authorities described as a “gruesome” homicide.

On Saturday afternoon, authorities found the bodies of five people, including a 5-months pregnant woman, inside a home on Jim Platt Road in Citronelle, Mobile County.

The victims were killed Saturday by firearms and several other weapons, said Capt. Paul Burch of the Mobile County Sheriff's Office.

"We have a horrible scene here," Mobile County District Attorney Ashley Rich told CNN affiliate WALA.

"I've been an assistant district attorney and now the elected DA, for six years, in total a 20-year career as a prosecutor, and I have never seen a scene where there were five people brutally and viciously murdered. That's what we have here."

Police arrested a man, identified as Derrick Ryan Dearman, in connection with the incident. He is now in custody.

Police received a call reporting a possible prowler at the home early Saturday morning. They arrived at the home, but found nothing suspicious.

The prowler, believed to be Dearman, had returned to the home early in the afternoon and allegedly killed the victims, Burch said.

Following the killings, Dearman allegedly kidnapped a woman and a 3-month-old baby from the home.

The woman, however, got away from the suspect and went to the Citronelle Police Department to report the kidnapping.

Later, Dearman surrendered at the Greene County Sheriff's Office and confessed to committing murder in Alabama. He has been charged with six counts of capital murder.
