A driver has been accused of drunkenly hitting a pedestrian with his vehicle in South Austin over the weekend, traveling at least a half-mile with the body before stopping at a beer garden, according to court documents.

Austin police officers responded at 10:36 p.m. Saturday to the 10000 block of Menchaca Road, just south of West Slaughter Lane.

Witnesses told officers they saw a 2014 white Ford Focus hit a person walking near Slaughter Lane and then drive south on Menchaca Road, an arrest affidavit says.

The body of the pedestrian, who police on Wednesday identified as 55-year-old Lee Martin Cagle, went through the Ford’s windshield. Cagle was found in the passenger seat of the vehicle a half-mile south from where the crash happened, the affidavit says.

The pedestrian had extreme, traumatic injuries to their head and some body parts had been detached, the affidavit says.

Witnesses said the driver, who was identified by police as 24-year-old Paul Joseph Garcia, calmly walked away from the vehicle after parking it south of where the pedestrian was hit, the affidavit says.

Garcia walked into South Austin Beer Garden at 10700 Menchaca Road barefoot and "in a manner that caught the attention of the other patrons," the affidavit says.

He was not served alcohol at the beer garden and officers detained him for further investigation.

Officers found Garcia with blood evidence and other debris on him, which matched "the blood and body tissue found coated in the interior of the vehicle," the affidavit says.

Police conducted sobriety tests on Garcia and placed him under arrest on a charge of driving while intoxicated.

Debris, including car parts and body parts, lined the road for a half-mile from where Cagle was hit, the affidavit says.

The evidence in the road, including the lack of braking marks, were consistent with a pedestrian being hit in the right lane of southbound Menchaca Road, the affidavit says.

Cagle was pushing a shopping cart in the road when they were hit, police said.

"The impact with the vehicle pushed the cart into a cluster of mailboxes with enough force to bend a two-inch diameter, galvanized steel post that supported mailboxes," the affidavit says.

Witnesses reported seeing the Ford without headlights on and being driven recklessly at a high speed.

Garcia was charged with intoxication manslaughter and accident involving injury because he was driving without regard for the safety of others, including "continuing to drive for one-half miles with a mangled corpse in the vehicle," the affidavit says.

He remained in the Travis County Correctional Complex on Tuesday with combined bail on the charges set at $110,000, according to online records.

Meanwhile, on Wednesday the Texas Alcoholic Beverage Commission said it was looking into the case after Garcia "indicated to Austin police he had consumed alcohol at multiple businesses prior to the crash."

"The investigation will seek to determine whether those businesses served alcohol to an intoxicated customer prior to the crash," a statement from the TABC said.

Texas law requires alcohol retailers to decline service to anyone showing signs of intoxication.

Businesses cited for selling alcohol to an intoxicated person could face a civil fine up to $7,200 as well as a temporary suspension of their license to sell alcohol, the TABC said.

Authorities have declined to name any of the businesses Garcia may have visited because the case remains under investigation.
