Police are crediting bystanders with potentially saving lives at Chick-Fil-A yesterday afternoon after police said 48-year-old Joseph Cimino went on a rampage.

Police said Cimino, who's lived in Lincoln for less than six months, became angry over his food order and started yelling and throwing food and trays.

That's when others stepped in.

"Despite a very tragic incident, I know there were actions on the part of employees and patrons that undoubtedly prevented additional tragedy," Lincoln Police Chief Jeff Bliemeister said.

Police said when Cimino couldn't be stopped, Special Agent Christopher Hall, with BNSF, pulled the trigger, fatally wounding Cimino.

They said Cimino had a stun gun and was making threatening gestures.

Cimino died after Hall and paramedics attempted to save his life.

"Investigators served a search warrant at Cimino's Lincoln home," Bliemeister said. "They seized digital evidence, and will be processing and analyzing the evidence. At this time, we have not discovered any evidence to support a premeditated motive."

That digital evidence could include social media accounts.

10/11 Now found a Twitter account under the name Joseph Francis Cimino, that shows a location of Lincoln, Nebraska.

The account was created Tuesday morning, and between 12:20 a.m., when the first tweet was sent out, and 5:38 a.m. when the last was published, the person who appears to be Cimino tweeted 401 times.

One of the tweets, which was sent at 5:21 a.m. said "You can't win. I regret nothing. It's just an f-ing chicken sandwich."

Cimino can be heard yelling a similar phrase in a witness video of the incident.

The Twitter account also links to a Youtube channel. On the channel, a man identifies himself as Joseph Francis Cimino.

There are nine videos that were posted on October 2nd, in which the man who said he's Cimino shares his story.

Police said any social media accounts of Cimino's will come up in their investigation, which is ongoing.

Lincoln Police have identified the man who was shot and killed by a uniformed Burlington Northern Santa Fe Special Agent after crashing his car into a Chick-fil-A on Tuesday.

Police said Joseph Cimino, 48, died at the SouthPointe Pavilions restaurant near 27th and Pine Lake Road around 1 p.m. on Tuesday.

According to Lincoln Police Chief Jeff Bliemeister, Cimino, a disgruntled customer, caused a disturbance inside the restaurant and was escorted out.

Cimino then climbed into his truck and drove backward through the west side of the restaurant.

Police said Cimino got out of his vehicle and continued to cause a disturbance and began punching a lemonade stand.

He made threatening statements to the Burlington Northern Special Agent who was in a marked vehicle in the drive-thru when the incident took place.

Bliemeister said the agent, Christopher Hall, saw employees jumping out of the drive-thru window in a panic, leading him to get out of his car and investigate.

He then realized Cimino was in possession of a stun gun, police said.

Police said Hall tried to create space between himself and Cimino, but Cimino kept moving toward him with the stun gun and making threats.

Eventually, Hall fired his gun, killing Cimino.

When Lincoln Police arrived, Hall was performing CPR. According to a BNSF spokesman, Hall is an 8-year veteran of the force.

Hall is scheduled to be interviewed by Lincoln Police on Wednesday.

Bliemeister said there no evidence to show the stun gun was ever used.

Police said the investigation is ongoing and there is no threat to the public. On Tuesday night, authorities served a search warrant at Cimino’s home where they seized digital evidence.

Bliemeister said so far in the investigation there is nothing to show Cimino's actions were premeditated.

The owner of Chick-fil-A has said that the restaurant will be closed until further notice.
