A man found not guilty by reason of insanity in 2014 after being charged with stabbing his father in the chest with a pocketknife — to see what it would be like to take a life — is behind bars again.

Bamboo Flute Blanchard, now 21, was released from custody Feb. 5, 2014, under conditions that included not drinking alcohol or using illegal substances, court records show.

But Blanchard was arrested Oct. 17 and charged with possession of LSD, jail records show. That arrest meant he had violated the terms of his release. Officials secured an arrest warrant for Blanchard, whose last known address was 2219 SE 49th Drive in Gainesville, and he was served Wednesday.

Just before 6 p.m. Monday, a Gainesville police officer spotted Blanchard on a scooter, swerving across two lanes in "a serpentine pattern" for several blocks.

When the officer pulled him over, she noted that he appeared nervous and "his heart could be seen beating through his shirt."

Blanchard would not let them search the scooter or his belongings, but police dog Axe alerted to the presence of drugs, and officers conducted their search, an arrest report shows.

In a backpack, which the officers noted smelled like cannabis, they found a wallet with several rectangular pieces of paper inside a cellophane wrapper that a field test said contained LSD, the report said. Blanchard immediately told the officers he didn't know what the papers were and that they weren't his.

In 2014, Blanchard was diagnosed with psychotic disorder and polysubstance dependence disorder after a June 2013 incident in which the then-18-year-old was in his family home when, without warning, he attacked his father, who had been lying down in his bedroom, records show.

Sheriff's deputies and Alachua County Fire Rescue responded to the scene of the stabbing, where they reported learning that Bamboo's younger brother had been using the knife for another purpose before laying it down on his bed. Blanchard then picked up the knife and gazed at it, saying, "I wonder what it would be like to take a life," deputies reported.

He then rubbed the knife on his chest near his heart and said he didn't think he could "handle it," the report said.

Blanchard then walked to his father's bedroom while being trailed by his younger brother and suddenly stabbed his father in the chest, deputies reported.

Alachua County Fire Rescue transported the elder Blanchard to UF Health Shands Hospital, where he told law enforcement he initially thought his son had punched him in the chest but looked down and saw he had been stabbed, according to the report. The father refused to give a sworn written statement regarding the events.

Blanchard also refused to speak to deputies and only grunted during his interview, deputies said.
