WINTER HAVEN, Fla. – Police investigators following up on last week’s mass shooting in Lakeland became involved in a car chase Monday that ended with a suspect being shot and killed.

The scene unfolded near the area of the area of 11th Street and 21st and Havendale Boulevard Monday afternoon. Polk County Sheriff Grady Judd said the incident unfolded Monday afternoon as part of an investigation by Lakeland police, ATF and FDLE.

Surveillance was being conducted on Alex Greene, 21, in connection with last week's shootings of 11 people.

When police tried to stop Greene, he drove off in a Chevy and ended up on a crowded Havendale Boulevard.

A Lakeland officer in an unmarked vehicle did a pit move to stop the Chevy, and Greene exited the vehicle. Authorites at a news conference said Green then ran to a restaurant, stole a vehicle, drove toward an officer and was shot. He then started driving erractically and crashed into a home security business.

Greene, who later died at a hospital, would have faced several charges, according to Judd.

Stephanie Lacey said she and her family were at Andrea's Family Restaurant, the business where Judd said a senior citizen was carjacked, at the time of the incident.

"We heard all the gunshots inside," Lacey said, though she told Spectrum News she didn't see what happened.

Lacey said her own car was hit at some point during the incident and pushed into the wall at Andrea's.

Nicholas Lambridis said he's owned Andrea's for 20 years, and his father owned the restaurant before that, beginning in 1986. He said nothing like this has ever happened before. Lambridis said he wasn't at the restaurant at the time.

"They called me, and I came," Lambridis said. "They were all panicking. It was scary. It was scary. She called me, like, 'There's a shooting'. I was like, 'Holy crap.' I thought somebody got shot in the restaurant. So, I'm just glad everybody's okay."

Joe Claussen manages Claussen's Fine Furniture next door to Andrea's. He said he didn't hear or see any of the commotion and only found out something had happened because of the law enforcement presence.

"I've never seen so many police officers at one time," Claussen said. "It's mind-boggling. You know, you wouldn't think that would happen in your neighborhood."

Across the street at the Mobil gas station, Tonia Davis said she heard about what happened from her boss. 

"I'm shocked. I'm really, really shocked all the way around. It's just - wow," Davis said. "I'm thankful nobody else was injured. I mean, sad that it ended like this because this is total nonsense, and it's just - it's wrong."
