Ashby was attending a court hearing for 19-year-old Christopher Ramirez-Rodriguez, who is accused of running a red light and killing Ashby’s 12-year-old nephew in July.

Steinberg was representing Ramirez-Rodriguez when Ashby allegedly “aggressively approached” him in the hallway outside the courtroom while trying “to see the defendant,” according to an arrest record obtained by the outlet.

Police said Steinberg pushed Ashby back to create space, after which Ashby allegedly carried out an “MMA-style takedown,” which left the longtime lawyer unconscious.

In an email sent Tuesday, Steinberg told CBS Colorado he also suffered a “shattered pelvis,” was in “serious pain,” and is scheduled to undergo surgery Thursday.
