NASSAU BAY, Texas -

A Houston-area woman was arrested early Thursday morning, accused of running over her husband and killing him after learning that he was cheating on her.

When asked about her husband's death, Clara Harris told News2Houston that, "It was an accident."

But Nassau Bay police said that they don't see it as an accident and said that Harris has been charged with first-degree murder.

The incident happened shortly before 9 p.m. Wednesday at the Hilton Nasa Clear Lake, Nasa Road 1, in Nassau Bay.

Investigators said that Clara Harris confronted her husband, David Lynn Harris, in the hotel's lobby.

"She said that she was just distraught over the marital problems that they were evidently having," Nassau Bay Police Lt. Joe Cashiola said.

The argument moved to the hotel's parking lot, where Clara Harris got behind the wheel of her Mercedes and ran her husband down, authorities said.

"Officers arrived on the scene and found the victim had been struck multiple times with the car," Cashiola said. "Since then, we have brought the wife up here for questioning (and) during the interview she has admitted her involvement."

Police said that Clara Harris had long suspected her husband was cheating on her, and that her suspicions were allegedly confirmed by a private investigator.

"She has admitted hiring a private investigation firm to follow her husband around," Cashiola said. "So there was some type of history. We're still digging into that."

Investigators said that David Harris' 16-year-old daughter from a previous marriage was in the car with his wife and watched him die.

The couple had two other children, who are currently staying with their grandparents, authorities said.

Both Clara and David Harris were dentists and lived in the town of Friendswood.

David Harris' patients reacted with shock after showing up at his dental office in the Clear Lake area and learning about what happened.

Clara Harris was taken to the Harris County Jail. She was released on a $30,000 bond.

She hired attorney George Parnham to represent her. Parnham is best known for representing Andrea Yates, the mother who drowned her five children.

David Harris' funeral is scheduled for Saturday at 1 p.m. at the South Park Funeral Home and Cemetery.
