BELTON — The man accused of opening fire on Killeen police officers in a deadly shootout last month appeared Thursday morning in Bell County District Court to face the charges against him.

Marvin Louis Guy, 49, of Killeen, pleaded not guilty to three counts of attempted capital murder in connection with the May 9 shooting.

Guy is accused of shooting at Killeen Police Department SWAT officers attempting to serve a narcotics search warrant at his Killeen apartment during the early morning hours.

Four officers were hit by the gunfire. Two of the officers were protected by their body armor. Another officer, Odis Denton, was hit in the leg. One of the shots struck Detective Charles “Chuck” Dinwiddie in the face. Dinwiddie died May 11.

Guy is in Bell County Jail on $3 million bond. His court-appointed defense lawyer, Mike White, asked district court Judge John Gauntt to lower that amount to between $10,000 and $100,000 per charge.

Guy’s younger half-brother, Garrett Galloway, testified that his family would be unable to raise the money necessary to bail Guy out pending his trial.

“We’re not rich,” said Galloway, one of Guy’s five siblings. “We don’t have a whole lot of money like that.”

Gauntt denied the bond reduction after Bell County prosecutors, led by District Attorney Henry Garza, presented Guy’s extensive criminal record. That record featured convictions dating back to the 1980s and included theft, domestic violence and bank robbery.

Under cross-examination, Galloway said he estimated Guy had spent at least half of his life in and out of prison.

As of Thursday morning, Guy had not been charged with Dinwiddie’s death. If charged and convicted, he could face the death penalty.

In late May, Garza told the Herald that the investigation into the veteran officer’s death was ongoing, and indicated additional charges were likely.

White said Tuesday he understood the need for Garza’s office to conduct a thorough investigation, but added that the specter of a possible capital murder charge did have an impact on the case against his client.

“If this is going to be a death penalty case, then I need to be preparing for that the moment I start representing my client,” White said. “Not four months later.”

Garza did not give any indication Tuesday when any additional charges would be brought against Guy.
