Daniel Pelosi Murder Case: Timeline of a Deadly Love Triangle

March 6, 2012— -- intro: In what was one of the most sensational trials in recent memory, New York electrician Daniel Pelosi, 41, was convicted of second-degree murder in the bludgeoning death of millionaire Wall Street investment banker Theodore Ammon, 52, seven years ago.

Prosecutors said he was angry over a proposed divorce settlement presented to Ammon's estranged wife, Generosa. Pelosi had been romantically involved with Generosa, and later married her.

Since being convicted in 2004, Pelosi says he is innocent and claims Generosa and his friend Christopher Parrino are responsible for Ted Ammon's murder.

"He was looking for an apartment and made an appointment and forgot about it. And the next day at the office he got an angry call from this woman who was the rental agent who said, 'how dare you stand me up' and he was sort of charmed. She was fiery," Shnayerson said.

Ammon spends thousands of dollars on contractors.

"There was a situation where a landscaper went with Generosa to a nursery and they picked out tulips," Michael Shnayerson told ABC News in a 2003 interview. "Over the weekend he came back to find her like a crazy woman ripping out all the tulips because the shade was wrong."

Ted frequently travels back and forth to New York City and Generosa suspects her husband is having an affair.

"I think that there were disturbing signs of temper, of kind of irrational anger that would flare especially when she felt in any way rejected or challenged," Shnayerson told ABC News in a 2003 interview.

Around Thanksgiving, she begins an affair with Daniel Pelosi, shown here in this undated photo.

Generosa had hired Pelosi, an electrician from Center Moriches, Long Island, to supervise the $4 million renovation of her new Fifth Avenue townhouse. Pelosi is a convicted felon who had been imprisoned twice for drunk driving.

"I went from a guy who walked into an electrical job to becoming the boss. I thought I hit lotto. I really did," Pelosi told ABC News in a 2003 interview.

Generosa flaunts her relationship with Pelosi. The new couple becomes a fixture in the Hamptons and moves in together at a swanky Upper East Side hotel.

"If you're a very vengeful, paranoid, irrational, soon-to-be ex-wife, what better punishment to inflict than shacking up in the Stanhope, in a $1,500 a night suite, with your new boyfriend, the electrician, and the kids right there in the next room and having him essentially be their surrogate father? It drove Ted absolutely nuts," Shnayerson told ABC News in a 2003 interview.

Investigators learn that Generosa will inherit the bulk of Ted Ammon's $80 million estate, despite the pending divorce, because Ammon had not updated his will before his death.

Mayne is left the run of the mansion along with $1 million. The twins receive the bulk of Generosa's multimillion-dollar fortune, but her husband Danny Pelosi receives nothing -- Generosa had cut him out of her will before she died.

Pelosi takes Generosa's ashes to their hangout, the bar at the Stanhope Hotel, shown here.

"I'm not saying I'm the most normal guy in the world. I do spontaneous, wacky things," Pelosi told ABC News in a 2003 interview. "My wife had just died. I'm not entitled to be a little wacky?"

Ted and Generosa's daughter Alexa Ammon lives with Kay Mayne in the East Hampton mansion. Her twin brother, Gregory, is sent to boarding school in New Hampshire.
