Ronchi’s lawyers want to call witnesses that include Galperina’s ex-husband, a psychiatrist, who would testify about a Benadryl overdose that Galperina, who was 42 when she died, allegedly administered to their son.
They also want to call a Swampscott police officer who investigated a report that Galperina had left two children unattended in a car parked outside a Vinnin Square grocery store months before her death.
The lawyers suggest that Galperina lied during both incidents, just as Ronchi says she did during their final, fatal argument.
The problem, Lowy pointed out, is that there’s no evidence Ronchi knew she was lying, nor any evidence that he knew of the earlier incidents, unless he takes the witness stand and testifies to that effect.
And even if Galperina lied in the past, “It doesn’t mean you can be murdered,” the judge said.
The lawyers also argued over the prosecution’s request to bar the use of Ronchi’s second statement to police.
After initially telling an officer that he “thought he’d killed his girlfriend,” he gives a more detailed but, prosecutors say, more self-serving statement, in which he says, “I had a moment of craziness. I had a moment of rage and anger,” then goes on to explain why he had brought the hunting knife (Galperina lived in “low-income housing,” he told police).
Ronchi then went on to tell officers that Galperina “says things to make me crazy.”
