court heard he had been diagnosed with obsessive compulsive disorder, and had been off and on his medication in the months leading up to sanche’s death. hamp said he went off his meds — against his doctor’s order — because he thought the medication was trying to brainwash him.
he also said sanche was worried that his heavy cannabis use might be contributing to his delusions, intrusive thoughts and false memories, so he quit smoking it two days before the stabbing.
“emily had been worried about me for months by the time my condition got really bad, and she was asking me to go to the hospital and quit smoking weed long before i did,” hamp wrote in a letter to sanche’s parents.
“i did not believe it at the time, but i now think this paranoia and ensuing psychosis were caused by the weed i was smoking. needless to say, i have quit for good,” he wrote in another letter to sanche’s cousin and best friend.
hamp sent his first set of apology letters from custody a month after the stabbing, in march 2022, but they were intercepted by police. another set of letters were re-sent to his parents, who gave them to police once they realized their relevance, pfefferle said.
witnesses testified, and hamp wrote in his letters, that sanche was working with
hamp’s parents to get him help and convince him to go to a hospital. court heard neither sanche nor hamp’s parents wanted to call authorities because they worried it would escalate his behaviour.
