(DAILYMAIL) — A Washington state man told his father during a chilling jailhouse phone call that he killed his 3-year-old son after taking pills and running out of gas on a remote road in southwestern Montana, according to new court documents.

Excerpts from the transcript of the call recorded the morning after Jeremy Cramer’s arrest on July 8 depict the 38-year-old Lacey man as rambling and sometimes incoherent.

‘I killed my own son and I don’t know why,’ Cramer said.
