(CBS) — She called in a robbery that never happened and arrested a woman for buying prescription drugs legally. She is the same police officer who had a violent struggle with a Chicago pastor.

Now, 2 Investigator Dave Savini is looking into other complaints about Michelle Morsi Murphy.

You may remember her as the cop who rammed her squad car into a vehicle with Rev. Catherine Brown and her two small children inside. Then she used pepper spray and pointed her gun at Brown in the 2013 encounter. 

Brown says she was trying to pull into her driveway when this altercation began.

“It’s a sad situation,” Brown says. “She needs to be off of the street.”

Within a year of Brown’s incident, two more serious cases were made against the officer. In one, an off-duty Morsi Murphy called 9-1-1 to report a man robbing a 7-Eleven convenience store when he was just buying snacks.

“I see a knife,” Murphy told a 911 operator.

But 7-Eleven surveillance footage shows there was no robbery and no knife. Murphy did not even seem clear on who she claimed robbed the store.

“In a gray hoodie, a white guy,” she said, at one point. At another point, she said, “He’s Mexican,” and, “There’s three male blacks.”

When those three men, who did nothing wrong, left the store, Murphy reacted in a panicked manner.

“Oh my God,” she said to the 9-1-1 operator. “They’re getting in the car. They’re getting in the car.”

The 9-1-1 operator told Morsi Murphy, who followed the suspects, to calm down:

“You’re an officer. Let’s behave like an officer.”

Murphy replied, “Yes, ma’am.”

While she followed the men, she reported another robbery.

“I guarantee you they robbed this gas station,” Murphy said.

Again not true, according to records from the Illinois Police Review Authority. The men never even stopped at the gas station, let alone robbed it.

On-duty officers caught up with the car. With guns drawn, they pulled the three men from the car — questioned, handcuffed and searched them.

Other officers responding to the 7-Eleven learned there was no robbery.

Another complaint against Morsi Murphy says she arrested a woman and locked her up overnight on a felony possession of a controlled substance charge.

The so-called illegal drug was actually a prescription still in a Walgreen’s bag the woman had just picked up for her 84-year-old mother.

CBS 2 tried unsuccessfully to talk to Morsi Murphy about these complaints.

As for Catherine Brown, she says Murphy should be held accountable.

IPRA is looking to reopen the case involving her and her children.

In the prescription drug arrest, a federal lawsuit against the City along with Morsi Murphy was settled.

She also received a 30-day suspension for the false robbery call.

During her ten years on the job, she’s had 19 complaints. Despite repeated requests, the city has not yet given CBS 2 all of those complaint records.

Chicago Police Department officials say they cannot comment on Brown’s allegations, because of her pending lawsuit. They say, however: “Individuals will be held accountable should any wrongdoing be discovered.”
