(CNN) -- A suspect is in custody in the murder of two young siblings during an attack at a home in Atlanta's northern suburbs, Gwinnett County Police spokesman Jake Smith said Thursday.
Two brothers, ages 1 and 4, were killed in Lawrenceville Wednesday night, CNN affiliate WGCL reported. A 4-year-old and an adult identified as the father were also injured, the affiliate said.
The adult escaped the attack and fled to a neighbor's house, the affiliate reported.
Two families lived in the home where the attack occurred, and the family that was attacked lived in the basement, police told the affiliate.
