(Good Morning America) The brother of a woman who was killed in car accident is accusing her insurance company of defending the person he said is her killer in an insurance legal dispute, including calling a witness to the stand against her.

Kaitlynn Fisher, called Katie by her brother and who had engineering degrees from Johns Hopkins University, died in a car accident on June 19, 2010 in Baltimore after another driver ran a red light. She was 24.

On Monday, Matthew Fisher, 33, her brother and a comedian based in Brooklyn, published a blog post, saying the insurance company Progressive “refused to pay the policy to my sister’s estate.”

Fisher wrote that “someday when you have your accident, I promise that there will be enough wiggle room for Progressive’s bottomless stack of in-house attorneys to make a court case out of it and to hammer at that court case until you or your surviving loved ones run out of money.”
