CHICAGO (CBS) – A family is grieving this Thanksgiving after a brother, uncle, and respected neighbor was stabbed to death while he was trying to break up a fight between a husband and wife.

It happened Wednesday night in Chicago’s Roseland neighborhood.

CBS 2 learned police are still looking for their suspect.

Neighbors say the last act of William Terry, just shows the type of person he was– selfless and caring.

On this Thanksgiving, Terry’s family is making funeral arrangements for the 55 year- old.

Blood stains a porch in the 10300 block of South Forest.

This porch is where 55 year- old William Terry came to rest after being stabbed multiple times Wednesday evening.

A neighbor, who didn’t want to be identified, saw Terry lying on the porch, moments before help arrived. She heard the commotion outside.

“I came out to the door with my husband and saw him laying there on the porch and he was bleeding pretty bad,” said the woman.

Police say Terry stepped- in to break-up a domestic dispute between a husband and wife.

Officers tell CBS 2, the husband went inside his home, grabbed a kitchen knife, and returned outside, stabbing Terry multiple times.

Neighbors tell CBS 2, the couple lived a few doors down from the home, where Terry lived with his sister.

“He evidentially had came back towards this way after he had been injured. He was maybe four doors down the street there, helping out with the situation,” said the neighbor.

This woman tells me Terry, also known as “Mike”, stayed with his sister to help her care for her children. He had a knack for relating to kids.

“The children on the block really loved him. He did a lot of things with the kids. Spent a lot of time with them throughout the summer, watching them on the block to make sure they was okay. It’s hard on their family. Very close family. Very hard on them. Yes, you know they all have broken hearts this morning.”

Chicago police say they know who they’re looking for, and the suspect took-off in a blue mini-van.
