According to the report, Onyeri had trailed the judge on Friday night as she was returning to her home in Austin and opened fire on her, injuring her extremely.
Onyeri was detained in Austin on suspicion of a recent theft in Louisiana and released on bond when he shot the judge when she was driving home in her SUV.
She was rushed to hospital in a serious condition on Friday and has since been upgraded to a stable condition.
The police say Kocurek had been receiving threats after presiding over controversial cases.
