Potentially damning testimony is expected in the murder trial of the prominent Utah doctor accused of drugging his own wife.
Prosecutors say Martin MacNeill's oath wasn't "do no harm" - but "don't get caught."
His own daughter agrees - and she could take the stand against him.
“Before this is all over, we may hear from more than one of Mr. MacNeill's children testifying against him. Today and this week we expect to hear from first responders who will talk about the inconsistencies in what he said that day and the odd behavior the day his wife died, CNN's Miguel Marquez reports.
Covering the case from the beginning, HLN's Nancy Grace gives further details, saying MacNeill is lying about what he allegedly said or did.
“When the EMTs and the neighbors were there, Oscar-winning performance,” she says. (SEE VIDEO BELOW)
“He became so belligerent and angry, they had to make him leave. The EMTs are testifying that's the only time in their whole career they thought they were going to be attacked. They thought MacNeill was going to attack them. That's crazy behavior. He was - he overdid it. The performance went over the top.”
