ALBANY, N.Y. (AP) — The final two months of Cachin Anderson’s life in New York’s prison system were filled with warnings he was a man in crisis.

He climbed on a sink and dove headfirst at the floor, saying he “wanted to end it and go home.” He urinated on guards. He hurled a can at one corrections officer and punched another in the face, knocking him out.

That behavior landed him in solitary confinement, a setting experts say is often unsuitable for people who are mentally ill or trying to hurt themselves. And there, Anderson killed himself on June 28, 2017, a death a state oversight board later said could have been prevented.

Prisoner advocates say Anderson’s death and others illustrate how New York’s prison system fails to ensure the safety of inmates who might hurt themselves if left alone in a cell.

New York state prison inmates in solitary confinement or long-term “keeplock” units, in which inmates are isolated, were over five times more likely to kill themselves than prisoners in general confinement, according to a report from the Department of Corrections and Community Supervision.

The report said that of the 130 inmate suicides from 2004 to 2013 in New York prisons, 30 were by prisoners in solitary or isolated housing, or a special treatment program.

New York has tried to curtail the use of solitary confinement. Earlier this year, Gov. Andrew Cuomo and legislative leaders announced a plan to restrict the isolation practice further by capping solitary confinement time to 30 days.

The state prison system has set out procedures designed to prevent suicides, too.

Correction officers watching over solitary confinement are required to make rounds every 30 minutes on an irregular basis.

Prisoners are also supposed to undergo a suicide prevention screening and a mental health assessment when they enter solitary confinement. During the screening process, prisoners found to be at an imminent suicide risk are put in the Residential Crisis Treatment Program, a separate unit inside the prison where correction officers make their rounds every 15 minutes, and each inmate is monitored under video, according to the Office of Mental Health.

Inmates in the program also have a private daily session with a mental health clinician. The program is used to find out which inmates need to be moved to the Central New York Psychiatric Center in Marcy, New York, for inpatient care.

But the rules aren’t always followed.

In its review of Anderson’s death, the Commission of Correction concluded that the 33-year-old, who was serving a 10-year sentence for involvement in an assault on a parking attendant, should have been put under a “one to one constant watch” until he could be seen by mental health staff.

“Had appropriate safety measures been taken, given Anderson’s recent suicidal threats and behavioral changes, his suicide may have been preventable,” the commission wrote in its report, obtained by The Associated Press through the Correctional Association of New York.

Anderson’s uncle, Larry Evans, a retired corrections officer in Connecticut, said his nephew should have been under closer supervision.

“If they knew that something was going on with him, he’s supposed to (be) in the unit where he’s supposed to be watched — period,” Evans said.

Prison suicides received national attention after Jeffrey Epstein, the millionaire accused of sex trafficking, killed himself at a federal jail in New York City.

Two jail guards responsible for monitoring Epstein the night he died have been indicted on charges that they falsified jail records to show they were checking on prisoners every 30 minutes, when they were actually sleeping and browsing the internet.
