Source: Chicago family murder investigation could go cold

CHICAGO (FOX 32 News) - The frustration is beginning to grow for Chicago Police as the investigation into the murder of six family members in Gage Park enters its fourth week. One source said this case could be another Brown’s Chicken case, referring to the Palatine restaurant massacre of seven people in 1993. It wasn’t solved until nine years later when a woman came forward and implicated her boyfriend and one of his friends.

In this case, the crime lab could be the key.

“There's obviously a lot of physical evidence, there's a lot of leads to follow up, we're working on it diligently,” said Gene Roy, Chief of Detectives

Chicago police are right now at the mercy of the State Police Crime Lab as they work to solve the murder of the Martinez family.

Detectives had requested a rush on some of the most critical forensic evidence gathered from the home where the bodies were discovered, but so far that material is still being processed.

Sources have told FOX 32 News that the focus of case is now looking at some kind of love triangle involving Maria Martinez and some men in her life. Cell phone records suggest Martinez may have been trying to make some of them jealous.

Around Christmas time she went through a nasty breakup with her then boyfriend, but a source said he visited her the Sunday before the murders.

“We're looking at a number of angles,” Roy said.

A Mexican Cartel connection to this case has reportedly been ruled out, but publicly the Chief of Detectives would not confirm that and he said at this point there are no suspects.

“We're talking to a number of people and we haven't ruled any motive in or out at this time,” Roy said.

Police said they are trying to be transparent with this investigation, but there is a lot of sensitive information that can't be released.

“If police put out all of that information publicly at this point, we're not going to be able to tell who's a credible witness and who is not. And at this point we have an obligation to that family to find out the truth of what happened,” said Anthony Guglielmi, Director of News Affairs

But at this stage, police are sure of one thing.

“I can tell you as a 30 year plus veteran of the Chicago Police Department that this particular incident is an isolated incident,” Chief Roy said.
