Double Homicide Under Investigation in Arlington Heights

ARLINGTON HEIGHTS, IL — Authorities have arrested a “person of interest” after a man and woman were found dead early Saturday in Arlington Heights. The incident is being investigated as a double homicide, according to a news release from the Arlington Heights Police Department. The names of the man and woman allegedly killed in the incident have not yet been officially released and the Cook County Medical Examiner’s Office will review the case on Sunday in an effort to determine a cause and manner of death.

Arlington Heights Police officers responded to a single-family home in the 0 to 99 block of S. Derbyshire for a well-being check after receiving a 911 call from the residence at about 12:32 a.m. Someone dialed 911 at that time from inside the residence but “no discernable conversation took place,” according to authorities.

Officers responded and found two people “with traumatic injuries,” according to police.

The man and woman were pronounced dead at the scene.

Authorities have not yet officially released the names of the victims but the Cook County Medical Examiner’s Office on Saturday evening notes Ann Martin, 71, and David Martin, 72, who lived at a home in the block where the murder was investigated, died at 12:55 a.m. Saturday at their home.

The Arlington Heights Police Department requested assistance from the Major Cade Assistance Team and was at the preliminary stage Saturday of “conducting a very complex investigation,” according to a news release.

Police said it did not appear there was any risk to the community and the incident was contained.
