Workers inside office building describe tense moments during shooting

LARGO, Fla. - For the folks at work at the Bayview Pavilion office building, Wednesday morning was anything but routine.

"Yeah, it was pretty scary, I was shaken up pretty bad," said Ivan Ellin -- who was on break from his job at the Matrix Medical Network in Suite 100 when he heard the shots ring out.

"We looked around the corner, and the whole glass to the front entrance was shattered."

According to authorities, a 52 year-old guy named Fred Michael Sumner -- distraught over his wife's alleged affair -- walked into the lobby, pulled a gun out of his pants and started shooting at least a half dozen times, before he apparently shot himself in the stomach.

"Uh, we got a 911 hang-up call and then I think we got a 911 open line," explained Lt. Mike Loux with Largo Police.  He says the initial calls came in at 9:28.  By quarter to ten, workers inside 15550 Lightwave Drive were tweeting graphic shots of police and paramedics working on the gunman on the lobby floor, and living through the sort of scenario one normally only sees in the movies.

"I heard the shots 'cause I was standing right here."  A woman who identified herself only as Lori recounted the moments of terror.  "I got up and started running, and I screamed at my coworkers to get up and go because I didn't know if it was down there or it was up here."  

"It sounded close?" I asked.  

"Yes," she continued.  "Very close.  So we ran next door in the other offices and went into a server room."

In those frantic moments right after, confusion and reunion as police discovered the gunman's wife wasn't even at work today.
