Man fatally shoots wife, himself in west suburban home: police
Police say the shooting in Downers Grove, IL that killed Dongwei Su and his wife, Yakun Su, in the 6400-block of Fairview Avenue was a murder-suicide.

DOWNERS GROVE, Ill. (WLS) -- Two people were found shot to death inside a home in west suburban Downers Grove on Tuesday night, police said.

Downers Grove police confirmed the shooting was a murder-suicide involving a husband and wife, who neighbors said had only lived in their home in the 6400-block of Fairview Avenue for about seven weeks. It was a lengthy investigation as police took about 14 hours to clear the scene.

Police said it all started with a physical altercation. Officers were called to the home at about 10:02 p.m., and several witnesses told police they saw a man with a gun inside a home and heard a gunshot.

Other neighbors said they didn't realize anything was wrong until they got a knock on their door.

"I went to the door and saw a police officer there," said Leo Conaghan. "Obviously, very nerve-wracking and scary."

The victims have been identified by police as 42-year-old Dongwei Su and his wife, 42-year-old Yakun Su.

Police said the husband allegedly grabbed a gun during an argument with his wife and shot her. Then, when police arrived on the scene, he was also found dead inside with a gunshot wound.

Neighbors believe the married couple had one son, but they said no one really knew the family.

"The neighbors had only lived there seven weeks," Conaghan said. "Never even got a chance to introduce myself or speak to them."

Neighbors said it's an eerie feeling, knowing what unfolded there. Police still had the home taped off on Wednesday afternoon, but the rest of the area has been cleared.
