A Bridgeport man is asking for the public's help in solving his brother's cold-case murder.

Jimmy Mullen, 49, says the pain he has endured over the past 18 years is very difficult to put into words.

Mullen says his brother, 31-year-old John Norwood of Bridgeport, was fatally stabbed in Norwalk on Halloween of 2000.

He is calling on the Norwalk Police Department to more aggressively seek evidence and witnesses in the nearly 20-year-old homicide.

Mullen's attorney says he will pressure officials to investigate more aggressively.

"This is an opportunity for the Norwalk Police Department to say, you know what, we're going to reach out to these families because they are important, because their lives do matter," says attorney Dennis Bradley.

Mullen says his brother was a gifted athlete and hard-working family man whose daughter will graduate this year from college.
