A woman who killed her cheating husband by mowing him down with her car in a jealous rage was ordered Friday to pay $3.75 million Wednesday to her in-laws.

Gerald and Mildred Harris had asked jurors to award them $5 million in compensation for lost companionship, pain and suffering, and lost financial support resulting from the death of their youngest son, David Harris.

Jurors deliberated for 10 hours before reaching their unanimous verdict. Their decision came after a week of often emotional testimony from the Harrises and their eldest son, Gerald Harris Jr.

When state District Judge David Bernal asked the jurors if they believed she was responsible for the "murder" of her husband, Clara Harris, clad in the orange prison jumpsuit she's worn throughout the trial, squeezed her eyes shut.

"The jury heard our story and returned an equitable decision," the elder Gerald Harris said. "We had an opportunity to tell the story of what a good man our son was and now the door is closed."

Clara Harris, 48, took the stand during the trial, but repeatedly invoked her Fifth Amendment right against self-incrimination. Her attorney, Dean Blumrosen, said he didn't want to risk having her say anything in the civil trial that might endanger her appeal of her 2003 murder conviction.

"She's not upset about the money," Blumrosen said Friday. He said she expected the lawsuit and expected to pay.

Harris may not be able to pay the full amount the jury awarded. She refused to give a certified financial statement before the trial.

"Clara has had a number of legal battles over the years, and she still has more to come," Blumrosen said. "I am not at liberty to discuss her finances."

Clara Harris repeatedly ran over David Harris, 44, with her Mercedes-Benz in July 2002 in the parking lot of the suburban Houston hotel where she had confronted him and his mistress several minutes earlier. The case garnered international attention, and she was convicted of murder in February 2003 and sentenced to 20 years in prison.

"She could have stopped and she didn't stop," jury forewoman Lorna Mullens said. "She kept running over him."

The civil jurors had to decide whether they should require Clara Harris to compensate the elder Harrises for their loss and, if so, how much that compensation should be.

Juror Cedric Wilson said he didn't believe he could put a dollar figure on a life, but was moved by Gerald Harris Sr.'s testimony about praying that God take him instead of David Harris when he first saw his son's dead body.

But juror Brandon Pauler said the panel also felt for Clara Harris's plight.

"I definitely think there was some empathy, some thoughts about what she'd been through as well," he said.

Joe Stephens and Richard Howell Jr., the attorneys representing the Harrises, told jurors they should award each of the Harrises $1 million for the loss of their son's companionship, $1 million for their mental anguish and an estimated $720,000 for the financial support their son had promised them in their later years.

Stephens and Howell also have urged jurors not to allow Clara Harris to "profit" from killing her husband.

"We think we will collect the money," Howell said Friday. He said Clara Harris has $150,000 remaining cash assets that are being held by the court while she serves her murder sentence, and may have retirement accounts and property in Colorado.

Blumrosen told jurors during closing arguments Thursday that his client was not interested in profiting from David Harris' death. On the contrary, he said, Clara Harris had ensured that 86 percent of the proceeds from the sale of the couple's lucrative dental and orthodontic practice went to their 8-year-old twin sons -- being raised by friends of Clara Harris -- and David Harris' 21-year-old daughter from a previous marriage. He said the proceeds from David Harris' insurance also went to his three children.
