Police: One of 3 killed in Round Rock wreck had stopped to help

One of the three victims killed in a crash on Interstate 35 in Round Rock early Sunday had stopped to help another driver, according to an arrest affidavit.

Maximo Ramirez, 49, of Greenville had gotten out of his vehicle to help the driver of a Toyota that had flipped onto its roof on the road, the affidavit released Tuesday said. As he was trying to assist, the Toyota was struck by another driver, later identified as Kearra Thomas of Temple, police said.

The impact of the collision threw Ramirez "some distance" away, where he died, according to the affidavit. The two other people killed in the three-vehicle crash were Agustin Guillen, 38, of Georgetown and Quinn Stegall, 21, of Round Rock.

Thomas, 22, was charged with manslaughter.

The affidavit did not contain other details about the wreck or how the other victims died. Round Rock police said Tuesday that the investigation into the crash still ongoing and declined to release further details.

Authorities were notified at 2:24 a.m. Sunday about the crash in the northbound lanes of the 1200 block of Interstate 35 North, just north of Texas 79, the affidavit said. The collision happened in a well-lit area and there was a video of it, according to the affidavit.

Multiple vehicles had slowed to a complete stop in the area before the crash, according to the affidavit, but it didn't say why the vehicles had stopped.

"It's clear that reasonable and prudent people would stop due to the accumulating traffic," according to the affidavit. "The defendant (Thomas) did not and kept traveling at what appeared to be highway speeds."

Thomas told police she was driving north in the middle lane of the interstate when she saw a car stop abruptly in front of her, so she veered into the left lane, the affidavit said. It said she told police she saw the Toyota on its roof and then collided with it.

Thomas said she was driving from from a restaurant in Austin to her home in Temple, police said. She said that before she went to the restaurant, she had drunk a Big Sipz around midnight, according to the affidavit. A Big Sipz is a canned cocktail that contains 16% alcohol by volume, the document said. It said Thomas also said she smoked marijuana before she went to the restaurant. Thomas gave a sample of her breath at the scene and it tested at .103 blood alcohol concentration, the affidavit said. The legal limit for Texas drivers is .08 blood alcohol concentration.

Thomas was being held at the Williamson County Jail on Tuesday with bail set at $300,000.
