How did Kutner died???

he shot himself, suicide

He committed suicide!! House was trying to prove that he was murdered

that morning House walked into his office and only Tuab and Foreman were there House asked "why is our little group missing brown and bi?" Tuab сказал(-а) "Thirteen is with the pasint and Kutner's dog is sick should be here by lunch" so lunch time rolls around and Kunter is not at work "look at the time, its twevle past Tuab is lieing for Kunter, go to his house,find out what или who he's doing" House tells them Foreman and Thirteen go to Kutner's house and Thirteen pulls out a key and unlocks the door when they walk in she says "wow man boy heaven, im surprized he ever leaves" they look around and Thirteen sees Kunter on the floor she runs to him and sees a gunshot wound to his head she starts CPR and Foreman picks up the phone and calls 911. after 3 минуты Thirteen leans against the постель, кровати she says "hes cold, Eric hes gone" Cuddy offeres time off and Foreman takes it, thirteen goes to his house and knocks on the door "Remy Hadley, i also answer to Thirteen i sometimes sleep with you" Foreman tells her she sould go. Funral день comes and Cameron, Chase, Cuddy, Wilson, Foreman and Thirteen go. Thirteen and Foreman, still not talking to each other help carry the casket. House goes to Kunter's house and looks at picuters of Kunter. at the end Foreman walks up Далее to Thirteen and takes her hand, she has a surprized look on her face.

He shot himself in the head. Cuddy points to her right temple while telling House they found gun powder residue.

Everyone thinks it was suicide except for House because House needed it to be еще than suicide because that would have meant that he missed the signs and that he was losing his "gift" which basically defines who he is. That's why House thought it was a murder, he just couldn't handle the fact that he didn't see this coming... so sad btw. :(
