Neighbors say owner, tenant lived in home

GLENVIEW, Ill. (WLS) -- A death investigation is underway at a north suburban house Monday.
Glenview police said they responded to a welfare check on Sunday at 7:31 p.m. on Glenview Road near Long Road just west of the Edens Expressway.
Officers said they found a dead man inside a house in the area.
Chopper 7 was over the scene on Monday morning, as crime scene tape surrounded the house, including the driveway.
The North Regional Major Crimes Task Force truck was also seen parked outside the house.
Police did not release further information about the victim.
Anyone with information regarding the case is urged to call police.

Neighbors were surprised by the discovery.
Investigators remained on the scene Monday afternoon, including forensic specialists. They walked in and out of the home, at times with bags of what appeared to be evidence.
"So I'm just wondering what could have happened?" neighbor Jerry Thomas said.
Thomas lives a couple doors down, along the 100-block of Glenview Road. Based on the police response Sunday evening, he said he quickly suspected something was wrong.
"It was clear that this was something, you know, really a little more in-depth and because the lights were here, and they stayed here most of the night," Thomas said.
Neighbors say two people lived in the home, the owner and a tenant. One neighbor said police took one person with them Sunday evening.
"They went inside and look around, and then they put their suits on, you know, whatever they were. And then they just come out with the body. We don't know who was it, you know," neighbor Wilfrido Morelos said.
Glenview police have not said if anyone is in custody.
"You always have to be careful. You always have to lock your doors. We do live close to the expressway; so, you never know what could happen. This is generally a pretty safe neighborhood. So, you know, you always have to be careful wherever you are," neighbor Julie Cook said.
