Oregon State Police have released a timeline of significant events regarding the Dennis Day investigation that spans almost an entire year.

On Thursday, Day's family made a public statement that confirmed that the body found on April 4, 2019, in Phoenix, Oregon, was that of the former Mickey Mouse Club member. While the time between the discovery of Day's body and the day he was positively identified to the public was about two months, police have documented specific events that date back to July 13, 2018.

The Phoenix Police Department and Jackson County Fire District #5 first responded to Day and his husband, Henry "Ernie" Caswell's home on Pine Street in mid-July of 2018 because Caswell had fallen several times. He was taken to the hospital, and later a care facility where he has been residing since. Just four days later, PPD learned that Day was going to visit friends and would return in several days. The department began to conduct several welfare checks at the home over the next couple of weeks.

On July 26, 2018, Oregon State Police responded to a domestic disturbance call on Highway 42 near milepost 30 in Coos County. They found a man and woman who were in possession of a car registered to Day. The woman driving was cited for driving while suspended and the vehicle was impounded, according to OSP.

The following day, PPD registered Day as missing in multiple databases, including the Law Enforcement Data System and the National Crime Information Center. Police then conducted another search of the home, but did not find any persons.

On August 8, 2018, PPD received a report of a "bad smell" coming from 510 Pine Street, Day's residence. Officers responded, but noted that "nothing observed or smelled in the area."

For over four months, there was no movement on the case. The next notable event did not occur until January 28, 2019, when a meeting was held that involved the PPD, OSP, and the Jackson County Sheriff's Office to discuss Day's case. The Sheriff’s office and OSP each provide a detective to assist.

A few more months passed until the PPD obtained the use of a cadaver dog on April 4, 2019. That is when a body was discovered inside the Phoenix home. The Jackson County Major Assault Death Investigation Unit (MADIU) was activated and OSP became the lead agency.

The OSP timeline ends on June 6, 2019 when the Medical Examiner's Office identified the body found at the Phoenix home as Dennis Day based on "strong circumstantial evidence."

According to police, the investigation is still ongoing.
