Update: KCSO Major Crimes unit has determined, based on their investigation, that 34 year old Matthew Ficken, as identified by the ME’s Office, killed his 68 year old mother and 72 year old father.
Detectives believe Matthew shot and killed his parents Thursday evening 1/10/19 or Friday morning 1/11/19 prior to their bodies being discovered this past Tuesday 1/15/19. Detectives believe Matthew killed himself as deputies were attempting to enter the house during their welfare check. Matthew appears to have lived in the house for several days after killing his parents and before killing himself.
Detectives believe a possible motive for the murders occurred when Matthew was told his mother was moving out of state and he would have to find his own place. His mother gave Matthew more than enough money to pay for his first and last month deposit on an apartment and additional expenses.
The investigation to date tends to show Matthew killed his parents because he didn’t want his Mom to move out of state and sell the family house out from under him.
