On the stand, Katleen Bouchard told jurors that, on several occasions, "My son would call me hysterically crying and said 'Mom, please come get me.'"

After Nico co-signed the lease for the Ghost Ship in late 2013, Katleen Bouchard said she met with Almena to try to encourage him to get proper permits for improving the structure, but that just Almena laughed at her and walked out of the meeting.
Earlier, a former Ghost Ship tenant and fire survivor, Carmen Brito, called the Ghost Ship "the most beautiful place" she'd ever lived.
And -- despite filing a civil lawsuit against the warehouse owner and the city of Oakland -- Brito said she made sure to exclude Almena and co-defendant Max Harris in that lawsuit.
