Catwoman (Volume 3) Issue 16

"Relentless, Part Five"
After this failure, he turned his attention once again to Catwoman. Threatening her friends and family, he coaxed her out for a confrontation. He was under the impression that she would enact her 'no kill code', however she did not as she shot him in the head and blew off his jaw, killing him. As well, Sylvia Sinclair was killed as well by Holly. Catwoman took these lives for her sister and her husband. However, it's shown that Roman Sionis survived her attack.
