(Newser) – In May of 2014, Willow Short received a heart transplant when she was just six days old. On Saturday, she was found shot to death along with the rest of her family in what police believe was a murder-suicide. The bodies of Mark Short, 40, Megan Short, 33, and children Willow, 2, Mark Jr., 5, and Lianna, 8, were found in their home in Sinking Spring, Pa., on Saturday afternoon when a relative called police after Megan didn't show up for a lunch date. Cops haven't revealed which parent they believe was responsible for the unfathomable crime, but they say a handwritten suicide note was found in the home and a handgun was found near the body of one of the adults, NBC Philadelphia reports.

Police say the couple had "domestic issues," and a friend in the neighborhood tells the Reading Eagle that Megan was planning to leave Mark and had been open about it, posting on Facebook that she needed people to help her move out on Friday. In 2014, the Eagle reported on Willow's struggle to survive her first week of life. In 2015, the Shorts and their struggle to obtain anti-rejection medicine for Willow were featured in a New York Times story. In April, Megan wrote a blog post about dealing with PTSD after Willow's illness, saying she still suffered from anxiety and nightmares and it had taken her two years to realize how badly she had been impacted by the ordeal, the Philadelphia Inquirer reports.
