62-year-od Pappas signed two properties over to Jeanette Sarah Spencer, an Ohio resident, on July 23 by Legal Express Texas.
Pappas had asked them to complete the paperwork on July 19 and acted strangely after launching proceedings, it has been revealed.
It was finalized on July 23, three days after Dr. Mark Hausknecht’s murder.
On July 20, Pappas is accused of following Dr. Mark Hausknecht on his bicycle as he cycled to work in Houston, Texas, and fatally shooting him.
Pappas was named on Wednesday by police who say the attack was an act of revenge.
The Motive for the murder, investigators say is that in 1997, the killer’s mother Julia Walker, died on Hausknecht’s operating table.
Houston Police are yet to find Pappas who they say is armed, dangerous and suicidal.

It’s not normal for people to be so antsy about transferring a property.
‘It just indicated he was premeditating this before it ever happened,’ Donaldson said.
It is not the first time Pappas has signed property over to Spencer, who also goes by the name of Mullet. Reportedly, the second time he signed the property over to her. The first time he attempted the estate transfer was in February 2017.

‘One of the tips included he fact that the suspect’s mother was a patient of the doctor and died during surgery over 20 years ago,’ he told a press conference on Wednesday. ‘It appears that this may be a 20-year-old grudge,’ he added.
On Tuesday night, before police obtained an arrest warrant for him and before his name became public, he sent a text message to a friend suggesting that he might kill himself.
