You mean if he would kill himself.Well I guess this is good that they are reaching out to include all voices.LB is a trusted voice.
I haven't read or heard anyone suggest that Daniel was suicidal. That was ANS role in the 'play'.
They have forty witnesses from what's been reported. They probably will have several people who have had extended contact with Daniel, like LB.
Of course, one of the two primary witnesses is dead. Now, there is only one story to be told about what happened in ANS hospital room.
