It has been almost 30 years since a Norwalk mother was attacked in her home while her young daughters slept. Her death remains unsolved.

Evelyn Colon was killed inside of her home on Ely Avenue on Aug. 23, 1990.

Police say her 9-year-old daughter heard her mother's screams and ran to her mother's room where she found her bleeding.

When the daughter tried to call 911, the phone didn't work. Police say it had been unplugged and used to beat 28-year-old Colon.

"It appears that she was struck first with the telephone, which was one of those larger square ones with the built-in answering machine system," said Lt. Art Weisgerber. "Struck with that in the forehead/head area and then at some point after that, shot twice."

The daughter ran to a neighbor for help. Police say the man performed CPR until officers arrived but it was too late.

Weisgerber took over the investigation while running the Cold Case Unit. Weisgerber says a neighbor told police he saw a man run out of the home nearby on Adamson Avenue.

The witness described the potential suspect as a black man who was between 18 and 22 years old at the time, 6 feet tall, thin and was wearing a white painter's hat.

Weisgerber says there's not a lot of DNA evidence in the case but says he was able to "develop partial DNA profiles from the phone."

He says it has not led to anything yet but it is a start.
