Four years ago, Anthony Tomaselli stopped breathing. His two grown daughters tried to resuscitate him until paramedics arrived. His own doctor ruled that the 85-year-old man died of natural causes due to his age and health problems.

Now deputies say it was murder.

“It was the ‘perfect’ murder,” Pinellas Sheriff Bob Gualtieri said Tuesday.

Tomaselli’s daughters actually conspired to kill him in 2015, the sheriff said, and they almost got away with it — until both became romantically involved with the same man.

A man called the agency on Feb. 13. The man, whose name was not released by the agency, told deputies that a women he was romantically involved with confessed to planning and murdering her father along with her sister.

---

He met Mary-Beth Tomaselli at a bar in August, the sheriff said, and they became intimate. Sometime later, she introduced him to her sister, Roberts. He then became romantically involved with her as well

---

quote:

The man told detectives Roberts acted “odd,” Gualtieri said. “It was clear something was troubling her,” Then, on Feb. 12, Roberts called the unidentified man to her home, the sheriff said, where she admitted to “euthanizing” her father.

---

The man took out his cell phone and started recording audio and video of their conversation, In it, Gualtieri said Roberts detailed what actually happened on March 5, 2015, the day the sisters are accused of carrying out their plot.

---

Gualtieri said the women gave their father an alcoholic beverage laced with an “excessive” amount of sleeping pills, hoping it would kill him. But Mary-Beth Tomaselli put too much alcohol in the drink, the sheriff said, diluting the pills and rendering them ineffective.

quote:

---

Their father lay on the couch, still moving, with labored breathing. So his daughters then tried to suffocate him with a pillow And when that didn’t work, they held down his arms, grabbed a rag, shoved it down his throat and pinched his nose
