But a source close to the star tells Fox News that her decision to end the animal's life would "not have been an act of malice."
"Mindy really loved her dog," the friend said. "It would have been more of a case where she just didn't want to leave the dog alone."
The troubled star, whose boyfriend, David Wilson, died of a self-inflicted gunshot wound in January, was reportedly under investigation at the time of her death. Police were concerned about details surrounding Wilson's passing.
