An Oak Harbor woman who was chased by a man with a machete and raped suffers from post traumatic stress disorder, depression and anxiety.

The trauma has given her nightmares and affected her work, she wrote in an impact statement.

A judge in Island County Superior Court last week sent the man, Johnson Knox, to prison for a minimum of 12 years and three months.

A sentencing review board will determine if he should be released after the minimum time.

Knox pleaded guilty earlier this year to rape in the second degree and possession with intent to deliver the drug MDMA, or Ecstasy.

Knox wrote an apology to both the victim and the court.

He wrote that he was “a slave” to LSD and took it all the time. It ruined his career in the Coast Guard, he wrote.

Knox told a Community Corrections officer that he had taken 20 hits of acid before he raped the woman and had drug-induced schizophrenia. He said the intent of the rape was not sexual and that he had the machete to protect the woman.

On Jan. 2, police respon-ded to a 911 report of a possible domestic assault at a home in housing for active-duty personnel of Naval Air Station Whidbey Island. An Oak Harbor police officer who entered the house encountered the victim as she was running down the stairs, screaming that “he” had a machete and was trying to kill her.

The officer drew his weapon, placed the victim behind him and ordered the man, later identified as Knox, to come down with his hands up. Knox was arrested.

The woman told investigators that Knox had become paranoid that night.

He threatened to kill her with a machete.

She tried to hide in a bathroom but came out after he threatened to kill himself. He then raped her.

In her impact statement, the woman recommended that Knox get rehab.

“I would like him to get some help,” she wrote.
