Harshman, 32, shot her four young daughters , called 911, then turned the gun on herself Feb. 10 in her home in residential Byron. The toxicology from Harshman’s autopsy revealed both ketamine and clonazepam, an anti-anxiety drug, in her system. Tranyelle Harshman’s home in Byron, Wyoming, sat quietly one day after a suspected murder suicide took the lives of three children and their mother. Blough knew of Harshman’s PTSD and post-partum depression and administered ketamine to her as psychiatric treatment, says the complaint. The complaint alleges that Blough “prescribed and permitted or directed Ms. Harshman to self-administer ketamine at home without medical supervision or safeguards.”On Feb. 10, says the complaint, Harshman ingested ketamine at her home.
