Harvey Louis Carignan (May 18, 1927 – March 6, 2023) was an American serial killer who was sentenced to life in prison for the murders of two women in the early 1970s.

[3] He was imprisoned at the Minnesota Correctional Facility – Oak Park Heights, Stillwater, MN, until his death in 2023.

[4] At the age of 10, Carignan returned to live with his mother after spending time with his aunt and uncle in North Dakota and Minnesota.

[4] He had a bedwetting issue as a child and was diagnosed as having childhood chorea and enuresis in a Mandan, North Dakota, reform school.

However, in 1951 Carignan won a new trial on his murder conviction on the grounds that his confession had been improperly obtained.

[9][10] Just months after his parole, Harvey and his brother, Clinton, who was also a parolee from Alcatraz, were arrested for burglary in Minnesota.

They were convicted of attempted third-degree burglary, and Harvey was returned to prison for four years, serving his time at USP Leavenworth.

Miller's body was found months later by two boys hiking on the Indian reservation north of Everett, Washington.

[4] Although he was considered the prime suspect, Carignan never faced charges in the murders of Brock or Miller due to a lack of evidence.

Carignan pleaded insanity, claiming God had ordered him to "kill whores and harlots."

Carignan pleaded guilty to second-degree murder for killing Schultz and received a 40-year sentence.

[15] Carignan died at Minnesota Correctional Facility – Oak Park Heights on March 6, 2023, at the age of 95.
