Linda Casey says:

Were fingerprints/dna taken of the inside lock? Was there corroborating evidence that the boyfriend was where he said he was at the time of the incident? Could he have been angrily texting her from within the apartment to give himself an alibi after killing her? Was there a crawl space in the ceiling where someone could have hidden? How many potentially fatal stab wounds were there? Where was the knife found? If the last blow cut her spinal cord, the knife should have still been in her hand or fallen appropriately next to the body. Where was the second knife (if she reportedly killed herself). What were the direction of the knife wounds? Were her hands bloody? Was she standing in one place or running around the house while supposedly killing herself? Did the neighbors hear anything? Is there a diary? What was the last phone call she made, to whom and at what time? So many questions.
