Staff at the Ramsey County jail were not conducting appropriate checks on inmates last year, according to a state review following an inmate's suicide last year.
The infractions occurred around the same time an inmate jumped to his death from a second-story common room, but they did not directly contribute to Christian Smalley's suicide, said a review by the Minnesota Department of Corrections.
The checks involve the inspection of inmates' cells.
"The health and welfare checks leading up to the time of this incident are out of compliance with facility policy, training and [state] rules," Senior Detention Facility Inspector Greg Croucher wrote to the Ramsey County Sheriff's Office in a letter last month.
Smalley, 57, of Oakdale, died on June 25. He was in custody for allegedly running over a woman with his pickup truck in the Target parking lot on University Avenue in St. Paul. The woman survived but suffered severe road rash, scrapes and bruises.
"Anytime somebody dies in the jail it's a tragedy," said Ramsey County Sheriff's Chief Deputy Steve Frazer. "There was no indication to us that anything had been done improperly to contribute to Mr. Smalley's death."
Frazer said jail staff were aware that Smalley was someone they should keep an eye on, but nothing had indicated that he was suicidal.
Whenever possible, he said, inmates are allowed access to the common room, where phones, tables, games and cards are available.
