A 7-year-old boy was among three people killed in a suspected murder-suicide in DeKalb County on Monday, according to police.

Officers were called at 3:15 p.m. to a home in the 3100 block of Briarcliff Road, according to a spokesperson for DeKalb police. There, investigators found two adults and a child dead, according to police.

“At this time, we believe it to be a murder-suicide,” police said in a statement. “The investigation is ongoing.”

The names of those killed were not released late Tuesday pending notification of family members, the DeKalb medical examiner’s office said. The two victims were a 7-year-old boy and a 49-year-old woman, while the suspect was a 51-year-old man, according to police.

Sagamore Hills Elementary School Principal Dr. Karen Williams sent a letter to parents confirming the child killed was one of her students.

“It is with deep sadness that I inform you about the tragic loss of one of our students,” Williams wrote. “Without question, this news is difficult to hear, and we want to extend our heartfelt condolences to the student’s family, friends and classmates.”

“As a strong and caring school community, we know many of you will want to help somehow,” the letter continued. “I will keep you informed if any assistance is needed. For now, I ask that you keep the family, students and staff in your thoughts.”
