Testimony has begun at the trial of a Kentucky doctor charged with killing his wife.
A jury will have to decide whether or not Dr. Steven Hall ran over his wife with a boat because of a love affair with another woman or did it happen by accident while he was trying to save her.
During the opening arguments, the prosecution attempted to paint the picture of a doctor married to one woman, Isabel Hall, but falling in love with another woman.
They say they had the witnesses to back it up.
Those witnesses Included the woman prosecutors claim Hall was falling for, his office assistant, Lory Devine.
"He told me for the last months he had feelings for me, but that he was keeping it under control," Devine testified.
The Commonwealth says Hall lost control of his boat last May on Herrington Lake, pushing his wife off the boat then running her over.
The defense paints a different picture, saying Hall and his wife were having great day on the boat for the anniversary when it went tragically wrong.
Halls attorney says when Isabel fell off the boat, Hall tried to move the boat closer.
The attorney says Isabel swam in front of the boat and was struck and killed, not by the propeller, but accidentally, by the sharp edge of the front of the boat.
Both sides say Isabel Hall had a large number of drugs in her system at the time of her death including pain killers for back pain and migraines.
Both sides agree the drugs could have made her unstable that day out on the lake.
If convicted, the maximum sentence Dr. Hall could face is life in prison.
