DENVER — A man, woman and girl who were shot at their home in southwest Denver on Thursday night are dead, the Denver Police Department said Friday morning.

Police responded to the shooting about 9:30 p.m. in the 3000 block of South Golden Way, northwest of Highway 285 and Sheridan Boulevard.

Neighbors identified the victims as Joseph McDaniels, his wife Althea and their daughter Christine.

According to the Denver Office of the Medical Examiner, all three died from multiple gunshot wounds.

Joseph was 48 years old, Althea was 37 and Christine was 11.

The couple’s son was uninjured.

Althea was pronounced dead at the scene. Joseph and Christina were taken to local hospitals, where they were pronounced dead.

Another woman was injured during the shooting, but not by gunfire. Her injuries are not life-threatening.

The family was planning to move to Mississippi.

Police said that following the shooting, they arrested 59-year-old Bustaman Kartabrata in northeast Denver. He is in custody for investigation of first-degree murder.

His motive is currently unknown. Police are still trying to determine the relationship between the suspect and the victims, but say they knew each other well.

DPD said investigators did not yet know whether Kartabrata planned the shooting. There were no signs of forced entry into the home.

“This is one of the most emotional cases that I’ve ever dealt with, and I’m not just talking about myself,” said DPD Division Chief of Investigations Joe Montoya. He said other first responders, victim advocates and hospital staff were deeply shaken.

“It was just tragic. It was terrible,” Montoya said.

About 4 p.m., a press release from Denver Public Schools indicated Christina was a student at Traylor Elementary School, which is just a few blocks from the McDaniels’ home.

DPS said its Family and Community Helpline staff are available to address concerns at: 720-423-3054.

Correction: An earlier version of this story said the couple’s son escaped through the window. It was actually the grandmother who escaped through the window.
