CINCINNATI —

An entire community is on edge as police search for a murder suspect who gunned down a landscaper in Corryville Tuesday.

Nicholas Kenan, 43, was a landscaper for Uptown Properties. He was shot to death on the job outside of an apartment complex on Bellevue Avenue.

His company said he was picked at random by the gunman who demanded money. Kenan didn’t have any, and he was shot to death on the spot.

The sound of the fatal gunfire was caught on a nearby doorbell camera.

“Just to hear about what happened was terrifying,” Chelsea Griffis said.

Griffis is a cleaning service employee for an Uptown Properties contractor. She was at work Thursday just a few feet from the place Kenan was shot. She's on high alert.

“I don't have my headphones, and I'm aware of my surroundings a lot more. I'm actually kind of scared,” Griffis said.

Some residents said they are moving out.

“It’s just really unsettling and scary,” Julia Ventura said. Her lease is up in a few weeks, but she would move out sooner if she could. “We definitely don't feel safe around here.”

Uptown Properties is offering a $10,000 reward for information leading to the arrest of a suspect. They’ve also helped to set up a GoFundMe for Kenan’s family.

Authorities in Washington say a woman was arrested and charged for allegedly pulling a gun on a convenience store worker after being thrown out of a store for not wearing a mask.

KIRO reported that on Jan. 27, Bellevue police responded to a disturbance at a gas station.

According to the Seattle Times, the employee told police that Angela Marie Nommensen pulled a gun on him after throwing her out for refusing to wear a mask as required by local rules.

The news outlets reported that Nommensen came into the store to get a receipt, but after being told several times to wear a mask, the clerk grabbed her shoulder and coat and escorted her out.

According to the newspaper, when the clerk got back inside the store, surveillance video captured Nommensen pulling a gun and pointing it at him.

She has since been charged with felony harassment, accused of threatening to kill the gas station clerk.

A customer at The Omaha Bakery in Nebraska ordered two turnovers, and in return put forth a huge tip.

"Everybody was freaking out in here, they were like 'you guys won't believe what just happened!'" employee Preston Rath said.

Rath thought he was doing a typical transaction at the bakery.

"He ordered two turnovers which came to $5 and as I'm ringing them up he kind of snickers a little bit as he turns the screen back to me," Rath said.

When the customer, Nicholas, turned the screen around, Rath noticed his $2,000 tip.

"And I was like that's wrong, you put too much of a tip in there. And he goes 'if you don't hit OK, I'm going to reach around and hit OK,'" Rath said.

"You hear about these things in big cities and you see it on the internet, but you never think it's going to happen at your business," owner Michelle Kaiser said.

Kaiser said the money will be dispersed between hourly employees only, no managers.

"He knew that it had been a rough time with COVID, he knew that people were struggling in general. He noticed our staff was working really, really hard," Kaiser said.

Rath hopes the kindness that Nicholas showed doesn't stop with him.

"You don't have to give random strangers $2,000 but even just saying 'have a good day' can help somebody go from a zero to a 10," he said.

Videos bring back happy memories of Mary Nielsen's two children.

"Teddy was just so sweet and loving. He was a mama's boy, you know," Nielsen said, "Emmy was exceptionally smart. She just had turned 5 in January, and you wouldn't have known it."

Now these memories are all Nielsen has, after her two children were found dead in their father's home last month.

"They had like a special bond, like, they were very, very close, and you could tell they were best friends," she said.

Those two little best friends, 5-year-old Emily and 3-year-old Teddy were staying with their father, Adam Price, last month.

Nielsen lives in Illinois.

"Saturday rolls around, and I was like, it was like 6:30, seven o'clock and I was like, 'the kids haven't called yet,' and I was like, 'they didn't call last night, either,'" Nielsen said.

According to Nielsen, a custody agreement required that the kids check in with her every day while visiting their dad.

"So I started calling him and blowing up his phone and texting him I'm like, 'even if you can't talk, like, I need to know the kids are safe,'" she said.

Nielsen posted on Facebook, asking if anyone had seen Price and the kids.

Meanwhile, police went to the house twice for welfare checks but say they had no cause to force their way in.

"I had a bad feeling in the pit of my stomach," Nielsen said.

Nielsen's friend offered to go over to the home. She said the friend found the door unlocked, and inside, the bodies of Emily and Teddy.

"I had to pull over, I was bawling," Nielsen said.

Price was gone. Authorities arrested him hours later in California.

Nielsen calls her past relationship with him abusive and said her children were the only reason she survived.

"I mean, I was very suicidal for a very long time during the relationship. Abusive relationships, like destroy you," she said.

Nielsen said she moved back in with her parents in Illinois to finish school and spend more time with her beloved kids. Now, as she mourns her beautiful, cheerful children, Nielsen wishes more would have been done to protect them.

"If someone had just listened to me when I said he was an unfit parent, they'd still be here, and it's still really hard," she said, "I just, the only thing that makes me feel like a tiny bit better is they don't ever have to see him again, but at the same time I'm missing them so so much."

Price is charged with two felony counts of child abuse resulting in death. His next court appearance is scheduled for June 15.
