Story

Tyrese was in her house when she heard the footsteps of someone approaching. She wrote the note "someone please help me" afraid that the intruder would hear her voice if she called 911. Smokey then found her and tried to take her. In the struggle Tyrese bled leaving the blood sample and was possibly knocked unconscious. Smokey wrote the note "you will never find her", dragged Tyrese to his car and left. Articles of evidence such as the earing, shoe, fabric, and iodine sample either came off during the struggle or while transporting the body, or was found in Tyrese's house.
