Frail and using a walker, Linda's 88-year-old father, was first to take the stand Wednesday morning.
He cried and said “that's my little girl" when the state showed him a picture of Linda, taken before the murder.
He told the jury he and his wife found their daughter's body at the bottom of a staircase in her south Tulsa home.
He said his grandson Hank Laird let them in the house that morning.
Linda's mother wasn't able to testify on the stand, but her statement was read to the jury. She said she called her daughter several times that morning and when she never got an answer she and her husband decided to go make sure nothing was wrong.
She said when she saw her daughter's body lying on the floor she ran over and started praying she was OK, but said Linda felt cold.
Linda's father testified when he felt how cold his daughter was he knew she was dead and told his wife to call 911.
The state played the 911 call for the jury.
“Oh my land, there's blood on the pillow,” her mother said. Then Linda's father was heard saying, “There's blood all over. She's stiff. She's dead."
The defense pointed out no blood was ever found on Laird or his clothing.
The state said Linda's son, walked out of the house once his grandparents showed up.
He was seen at a coffee shop a few hours after his mother's body was found and police officers arrested him the next day, January 23, 2013 at a Tulsa home.
Many remember him by the pink hair he had at the time.
The pink hair is now back to its natural color, red.The state's star witness, Josiah Sklar, took the stand in the afternoon. Sklar basically lived with the Lairds and was there the night of the murder.
Throughout the testimony Wednesday, Laird sat stone-cold. He often times looked down at the table, but sometimes would scan the room, he even yawned a few times.
The only time he showed any emotion was as his grandfather walked out. He couldn't take his eyes off his grandfather and he smiled sweetly until he was gone.
The trial will continue Thursday morning.
