Det. Lt. Stephen Fitzpatrick says Gross and Coppola were in a romantic relationship for many years.
"They had a very contentious relationship with violence and stealing of money," Fitzpatrick said.
According to investigators, Gross went to Coppola's home to confront him over money, and the two got into a physical fight. Gross allegedly beat Coppola using a pot or a pan from the kitchen, killing him.
Fitzpatrick says Gross set the house on fire in an attempt to cover up the alleged murder and left the scene in a taxi.
Gross allegedly stole jewelry from Coppola's home before setting the fire and later pawned it.
She is facing murder and arson charges.
