Hartman was found in her wheelchair inside of her locked Ōmao home on Pune’e Road, according to prosecutors.
Police then obtained a search warrant and found Hartman’s keys for her home and vehicle as well as shorts stained with her blood inside of Grewer’s rental unit. Grewer was also observed to have fresh scratches on his chest, according to police.
Evidence also revealed that Grewer’s DNA had been found on Hartman’s fingertips and under her fingernails. Prosecuting Attorney Kollar said, “a measure of justice” was achieved through the guilty verdict.
“Nothing we do can bring Joellen Hartman back to life, but today we achieved a measure of justice. I am grateful to each person who helped bring this case to this verdict and I am thankful to the jurors for their service. Trying a highly complex case like this during a pandemic was quite an undertaking and it took a first-rate team of attorneys, victim advocates, clerks, and many others to get the job done – and they delivered in exemplary fashion. We will continue holding Ms. Hartman’s friends and family in our thoughts.JUSTIN KOLLAR, KAUAI PROSECUTING ATTORNEY
