When they weren't together, the couple exchanged as many as 100 text messages a day. Even while he was at the hospital, supposedly doting on Connie Hoagland, Larry Hoagland was sending messages and even a photo to his secret lover.
"When he rededicated his life to his wife, about 40 minutes after he got to the hospital he was out in the hallway taking pictures of himself in that fish-eye mirror and texting her," Luke said. "He sent it to her email, says, 'I love you Lee Ann, I wished you were here.'"
Both Connie Hoagland and Lee Ann Rupert testified in court last April, at Larry Hoagland's attempted murder trial. Rupert told the court that Hoagland told her that he was in the process of getting a divorce from his wife and had already moved out of their home. She and Larry Hoagland often spoke of getting married. She also said she knew nothing of Hoagland's pipe bomb scheme. Det. Luke said the Sheriff's department investigation confirmed that Rupert was unaware of the pipe bomb plot.
Rupert did not respond to phone messages from "20/20" seeking an interview.
Larry Hoagland testified that he never mentioned divorce to his wife. He said he only planned to tell her he wanted a divorce as he was on his way out the door.
"It sounds very cowardly, but that's what I was going to do," he said in court.
It was more than just his affair that police -- working with the Bureau of Alcohol, Tobacco, Firearms and Explosives -- used to build a case against Larry Hoagland. In his wallet, they found scraps of paper for cell phones used for the operation of a different pipe bomb -- one that failed to detonate just two blocks from the Hoaglands' home. Police found that botched bomb just two weeks before the explosion that injured Connie Hoagland.
At his trial, Larry Hoagland claimed that the numbers were given to him "by a transient that I call Jerry."
"He said, 'Here, take my phone number,'" Hoagland said.
The jury in the trial didn't buy his story. In May 2012, they found Larry Hoagland guilty of premeditated attempted murder and other charges. He was later sentenced to life plus 13 years in jail.
Larry Hoagland continues to maintain that he had nothing to do with the attempt on Connie Hoagland's life. Larry Hoagland's attorney denied a "20/20" request for an interview.
