Sousa has worked at the Dunkin Donuts at 339 Main Street in Waterville for several years according to employees there. 

"I believe Nick did something to her," Meghan Legasse, who has known Sousa for more than three years and is now her manager at work, told NEWS CENTER Maine on Wednesday. 

Legasse says she is not just Sousa's boss but her friend. "(Lovejoy) threatens her daily," Legasse said that Lovejoy had held guns to Sousa's head and sent threatening texts to the mother of his twin girls. 

Legasse says it is not like Sousa to disappear and that she would never walk away from her girls. 

Elizabeth O'Neil told NEWS CENTER Maine she last saw her co-worker on Oct. 21, Monday. Sousa was leaving work around noon and O'Neil was just arriving. 

O'Neil said that Sousa had been fighting with her boyfriend Lovejoy "a lot" about personal stuff. She said Sousa is a good mother who loves her daughters a lot. 

Staff at the Main Street Dunkin' Donuts are very upset about Sousa's disappearance according to O'Neil who said she was worried for Sousa's twin girls and had been crying all morning. 

Lovejoy was later taken to the Kennebec County Jail, where he is being held in lieu of $2,000 bail.

A team of State Police detectives and evidence technicians are in Waterville and have joined Waterville Police in the investigation. 

Anyone who has seen Sousa or has information on her whereabouts is asked to call Waterville Police at (207) 680-4700 extension 4513.
