>> A troubling pattern of lapses in patient care at a local safety net hospital, including multiple resulting in deaths.

That's the finding of a new W t Tw News investigation into Roseland Community Hospital on the far South Side.

In one instance, a patient who regulators say the hospital failed to properly monitor and keep from leaving is now charged with murder.

Please be aware.

This story also includes discussion of suicide or Nick Bloomberg joins us now with more.

tell us the details of that case will bring us.

We spent several weeks going through hospital regulatory reports.

Police reports court filings and more to learn about the case of a south suburban man named Paul Patton.

>> Now, according to records we obtained, he called 9-1-1 in October during a heated argument with his wife to Lola Patton said he'd been drinking heavily and was worried he might harm himself or his wife.

He was taken by ambulance to Roseland Community Hospital, regulatory reports show a patient clearly matching Patton's description was taken to the emergency department.

Now since Patton said he was suicidal, there are a number of steps that regulators and experts say should be taken to ensure his safety.

That includes taking him to a private area, putting one-on-one monitoring in place as well as the suicide assessment.

The report we obtained shows none of those things happened.

Now after about an hour and a half documents show Patton left the hospital returned home and got into another argument with his wife.

Prosecutors say he then fatally stabbed his wife while she was on the phone with 9-1-1, Patton now faces 2 counts of first-degree murder.

His attorney did not respond to a request for comment and we were unable to get in contact with anyone from the Patton family.

Nick, what kind of consequences could the hospital face for failing to monitor a suicide patients?

What Rosen has already been hit with what's called an immediate jeopardy finding that is the most serious possible citation under federal guidelines.

It means a healthcare facility failed in a way that that did or was likely to cause serious harm.

And that needs immediate correction.

Now W T Tw News and ProPublica previously reported on those kinds of citations and other neglect allegations at Roseland in the 3 years since that story records we obtained from the state public Health Department show Roseland has received at least 4 more immediate jeopardy citations, including in Patton's case.

Now, in another instance, regulators say the hospital failed to properly stabilize a pregnant patient before transferring her to another hospital.

She subsequently lost that baby.

Another case revolves around someone being treated for a possible drug overdose who was discharged after becoming hostile and left unattended in a waiting area for several hours.

Despite some staffers warning they appeared unwell.

Now the 4th case involves a person with mental illness who was discharged to the wrong location and whose legal guardian wasn't properly notified of their treatment.

And then what do community members hope to that?

There's a petition with more than 1500 signatures.

It was launched by a neighborhood activists calling for a new hospital CEO and leadership.

They also want the state to step in and provide some oversight here as well as for the community to have a say in any potential leadership changes through an advisory board or something similar like that.

And we should note Brandis that Rosen did not respond to multiple requests for comment.

Some concerning issues there.
