A woman was fatally shot during a carjacking while spending the night supporting a friend through chemotherapy in the Houston Heights neighborhood of Texas. The suspect faces capital murder, federal firearms, and carjacking charges, which carry the possibility of life in prison or the death penalty, authorities said.

The victim, Marietta Allison, spent March 6 at MD Anderson Cancer Treatment Center before driving her friend, Cassie Daniel, and the friend’s father home, authorities said. In a Facebook post on March 8, Daniel recounted the day her friend was murdered.

"Friday I was at MD Anderson for my second chemo treatment. My ‘sis’ Marietta drove me and Dad," Daniel said. The group left the treatment center late and drove to a friend’s house. When no parking was available, Allison circled the block.

"There wasn’t any parking, so Marietta had driven around the block to find a parking spot and we heard the gunshot,” Daniel wrote.

Daniel said she tried calling Allison but received no answer. “My friend went down to look for Marietta because it had been talking [sic] longer than it should for her to walk back. I tried calling her—no answer,” she wrote.

She then called Allison’s husband to see if he could “find her phone.” Soon after, she heard sirens.

According to a federal criminal complaint, Allison had parked a 2019 Toyota Highlander and was walking back toward the apartment when witnesses heard “a female scream, followed by a loud popping sound."

Authorities allege that 18-year-old Darius Dewayne Hall shot Allison, raided her purse, and then drove away in the stolen SUV.

Prosecutors say Allison suffered a gunshot wound to the neck. She was taken to Memorial Hermann Hospital, where she was pronounced dead shortly after midnight.

“We were later told that her heart stopped immediately. When he shot her in the neck,” Daniel wrote. “Yet both first responders and the ER gave CPR but her heart never restarted.”

Officers later located the stolen Toyota Highlander and attempted a traffic stop, but the driver fled, according to the federal complaint. The pursuit ended shortly after the driver crashed the SUV.

Authorities say Hall ran from the vehicle, attempted to evade officers on foot, and changed clothes before he was taken into custody.

Federal prosecutors announced on March 10 that Hall is charged with carjacking and firearms offenses in the fatal shooting. He remains jailed on a capital murder charge filed in Harris County District Court.

Court records allege Hall intentionally killed Allison by shooting her with a firearm while committing or attempting to commit robbery.

“The federal carjacking charge carries up to a life sentence or the possibility of death,” the U.S. attorney’s office said. Prosecutors added he “also faces a minimum of 10 years and up to life if convicted of the related firearms offense.” Both charges also carry a possible $250,000 fine.

According to federal law, if death results from a carjacking, the defendant faces a lifetime sentence or the death penalty.
