Kittie bassist Trish Doan has passed away. She was 31 years old.

The band announced Doan’s passing on Facebook earlier this week (2/13):

According to Loudwire, frontwoman Morgan Lander also took to social media to address Doan’s death:

I have been struggling with the right words and having trouble processing the loss of someone who I counted among my best friends. Thank you to everyone for reaching out, your kind words, stories and photos. She was truly loved more than we all could ever know. From the moment I met Trish there was an instant bond between us that I could never really explain. Perhaps we saw within each other many of the things that were reflected within ourselves; qualities that made us intrinsically who we are, and we clung to that dearly. I think she also looked up to me a great deal, and I appreciated the responsibility of what that meant as a friend. We grew up together to become better people than who we once were and through everything she and I always remained very close, part of the support system we both needed. I loved her like a sister and she was a part of my family, now forever changed. She with her boundless energy, 10,000 ideas and a fiery, vibrant light that could never be extinguished, even now. I love you Trish and I miss you.
