SEATTLE (AP) — Isaac Zamora’s mother begged him to get help when he was released from jail a month ago. State and federal laws prevented her from doing much more for the man who has now been arrested after a shooting spree in rural northwest Washington that left six people dead and four wounded.

The Tuesday afternoon rampage began close to the home of Zamora’s mother, Dennise Zamora, near Alger, about 70 miles north of Seattle. It continued amid a high-speed police pursuit on Interstate 5 and ended in Mount Vernon, about 20 miles south of Alger, when Zamora surrendered at a sheriff’s office.

In the wake of the shootings, Dennise Zamora has said she wants people to know that “my son was desperately mentally ill and we’ve been trying to get him help.”

If someone resists help in Washington, a family member must demonstrate he is a danger to society or himself or is “gravely disabled” before he can be involuntarily admitted to a mental hospital.

Washington’s laws offer more options for involuntary commitment than most other states, said Ron Honberg, legal director of the Arlington, Va.-based National Alliance on Mental Illness. But Washington families still can’t petition in court for their adult relatives to get treatment.

The laws were designed to protect the rights of the individual, explains David Weston, chief of mental health services with the mental health division of the Washington Department of Social and Health Services.

Many states, including Washington, also struggle to pay for mental health services.

That might be part of the explanation why Zamora, who was ordered by a judge to seek a mental health evaluation as soon as he was released from jail in August, had not yet seen a counselor. He served six months for cocaine possession.

His evaluation was delayed while his parole officer tried to find money to pay for it, said Chad Lewis, spokesman for the state Department of Corrections, which was supervising Zamora after his release.

Zamora, 28, is being held on $5 million bail for investigation of murder and attempted murder.

According to friends and family, the gunman had been in and out of hospitals over the years, seeking help for mental illness.

In Zamora’s case, the treatment was mostly involuntary, but Weston said the majority of mental health services are provided to people who ask for help.

Fewer than one-third of adults with a diagnosable mental disorder receive any mental health services in a given year, according to a U.S. Department of Health and Human Services report on mental health.

Honberg called it a sad irony that in most cases, the 8.1 million adults with schizophrenia or bipolar disorder in the United States are being cared for by their families, who have no legal standing.

Friends of Zamora said he had been diagnosed with both mental illnesses, but state officials would not say if such a diagnosis was part of his file.
