While Connecticut Waits, Police Talk Newtown Shooting Across U.S.

Delvecchia also is a keynote speaker that same week for a conference in Dallas sponsored by the Dallas Children's Advocacy Center. He will be joined by Sgt. Joshua Pattberg, who has spoken at other conferences across the country.

Their topic will be "Lessons Learned from the Sandy Hook Elementary School Shooting." On the advocacy center's web page, the group's CEO writes: "We will again take you behind the scenes of many notable cases, such as the Sandy Hook Elementary School shooting, which details what happened in Newtown, Connecticut, on the day 20 children and six adults were murdered by Adam Lanza."

Vance said that the investigation is proceeding and that traveling to conferences is not interfering.

Sedensky also said he isn't worried that the conference will slow down the effort to finish the report.

"This is not the only case [the state police officials] are involved in. The state police are trying to free them up to finish the Newtown investigation because everyone recognizes its importance,'' Sedensky said. "[Attending conferences] is not impacting their investigation."

There will be a second presentation at the Dallas conference by Newtown police officer David Kullgren, who will talk about "responding to the active shooting at the Sandy Hook Elementary School."

Kullgren is not the only Newtown officer to talk at a conference about the department's response on Dec. 14. Officers have gone to Maine, Tennessee, Michigan and Florida.

In Orlando two weeks ago, about 800 law enforcement officers who attended a conference heard the first 10 minutes of the police dispatch tape from the morning of the school shooting played by officers Leonard Penna and Jason Flynn, according to accounts reported by the Daytona News Journal and Huffington Post. Sedensky has denied The Courant's request to release the dispatch tape and 911 calls, saying they are part of the ongoing investigation.

After playing the dispatch tape, Penna then graphically described for the audience what he saw that day, according to the Daytona News Journal and Huffington Post.

Penna told the group when he pulled into the parking lot he saw a black car with the passenger's door wide open and two black jackets laid on the ground. Penna said that he assumed it was the shooter's car and that since there were two jackets, there probably were two shooters.

When Penna and other officers entered the school through the boiler room, they were hit with "a powerful odor of gunpowder," the report said.

"At that point, I saw two lifeless bodies and the biggest pool of blood I've ever seen in my life," according to the reports.

According to the Daytona News Journal report, Penna said he saw another group of officers enter a classroom on the left and he continued to the next room.

"I was never prepared to see what I saw — the first thing I saw was an alive first-grade girl covered in blood and she just says 'I'm scared and I want to go home,'" Penna said.

He then entered into the first classroom and heard a shot. "My first thought was one of our guys shot him," he said. So he ran back, grabbed the girl, and took her out — before learning that the shooter had shot himself.

Penna, Flynn and a third officer, Lt. Richard Robinson, then held a question-and-answer session with the conference-goers, the News-Journal reported.

Sedensky said the Newtown officers are witnesses, not part of the investigative team, so they did not have to clear their comments with him first. Sedensky said the dispatch tape was information readily available on the Internet and did not compromise the investigation.
