The Major Case Squad said Saturday it is looking for a person of interest in connection with the killing of a Cahokia woman found shot to death in her home Friday.
Antrell Teen, who is in his 30s and known to frequent the Overland, Mo., area, was named as the person of interest.
Detectives also are looking for a blue 2001 BMW X5 car that Teen is known to drive.
Teen is described as armed and dangerous. He is a black male who is 5-feet, 11 inches tall and weighs 175 pounds.
Cassandra Holman, 45, was shot several times in her home in the 100 block of Kenneth Street.
Holman was able to run to a neighbor's house for help but she died at Touchette Regional Hospital in Centreville two hours after police received an early-morning call reporting a home invasion at her residence.
During the home invasion, another person was shot and later received treatment for non-life threatening injuries.
Along with Teen, investigators are looking for a woman in connection with the killing but they did not release her name.
Anyone with any information is urged to call 618-332-4248.
