Arlington Heights police are questioning a person of interest after they found two people dead inside a home early Saturday in the northwest suburb.
Officers received a 911 call about 12:30 a.m. from the first block of South Derbyshire Lane, but the person on the other line did not say anything, according to a statement from Arlington Heights police.
When officers arrived, they found David and Anne Martin, 72 and 71, dead with “traumatic injuries.”
A person of interest was taken into custody Saturday morning, police said. The incident is being investigated as a double homicide.
Autopsies conducted Sunday concluded they both died from multiple stab wounds. Their deaths have been considered homicides, according to the Cook County medical examiner’s office.
Police said the incident was “contained” and that they don’t think there is any risk to the community.
A neighbor and longtime friend of the the victims said they were “very friendly” and that news of their deaths came as a shock.
“They were incredible neighbors; lived across the street. Always said ‘hi’ and were active in the community. We are a very close knit community and we are all devastated by the loss,” the neighbor, who asked not to be identified, said.
Arlington Heights detectives and forensic technicians are investigating with support from the Major Case Assistance Team.
