UPDATE: West Palm Beach police have confirmed that Jennifer Berman was identified by the medical examiner as the woman inside the home where the murder suicide happened.
Police released the 911 calls in the case of a murder/suicide in West Palm Beach in which a woman and two teens died.
West Palm Beach Police say the woman, whom they still haven't officially identified, 16-year-old Alexander Berman and his sister 15-year-old Jacqueline Berman were all discovered dead Monday morning.
Richard Berman said he and a family member received an email from his ex-wife that raised safety concerns.
On the 911 call he said, "My ex-wife said she was going to harm the kids and that I should get over there ASAP."
Police say the threatening email was sent just one hour before he dialed 911.
"She sent me an email that she did the best thing for our family and then she sent her cousin a text that she was going to kill the kids and herself," Berman said to the 911 dispatcher.
The dispatcher then asked if the woman had any weapons. "I remember she had her dad's old rifles," Berman responded.
Detectives say they are trying to determine exactly what happened after the email was sent and before the frantic 911 call.
"What we have to be cautious of is not to rush to judgment as to how they died. And that is why we wait for the medical examiner," said West Palm Beach Police spokesman David Lefont.
Close friends of Richard Berman say he is too upset to speak.
This came as a giant shock. We are trying to cope with the shock right now. Family and friends are beside ourselves. We did not see this coming and this is one of those things that hits you like lightning," said family spokesman Jay Kaufman.
