A man who was shot by Houston police officers after he allegedly fired several shots in Tranquility Park appeared in court Friday.

Attorney and mental health advocate George Parnham is representing Joshua Anthony Twohig, who has been charged with aggravated assault against a public servant.

Houston police said Twohig, 21, fired a high-powered rifle in Tranquility Park about 5 p.m. Nov. 21.

Parnham said Twohig is severely mentally ill and never wanted to hurt anyone but himself.

"He was not with Occupy Houston. He was out there all by himself and quite frankly intended to commit suicide by cop and that was almost successful," said Parnham.

A pair of bike patrol officers shot Twohig in the leg when he pointed the rifle at them.

While Parnham would not say whether he will launch a mental health defense in the case, he has had Twohig evaluated by a psychiatrist and is awaiting the results.

"He was delusional, exhibited paranoia," Parnham said.

Parnham also said diaries found with Twohig on the day of the shooting, along with other items in his home, show his client felt there was some type of massive conspiracy bearing down on him. Parnham added Twohig is in "much better spirits" since he has been taking his medication on a regular basis.

Prosecutors asked to judge to raise Twohig's bond because of his mental instability. The judge raised the bond amount from $30,000 to $100,000.

Twohig is being housed in the medical ward of the Harris County Jail and is undergoing psychiatric care.
