(CNN)With prosecutors nearing the end of their case, attorneys for Alex Murdaugh are strongly considering putting the disgraced former South Carolina attorney on the stand in his own defense in the trial for the killings of his wife and son, according to a source familiar with the defense's thinking.
The defense is expected to make the decision in the next couple of days, the source said. But the decision will be made late and perhaps at the last second, the source said, after the prosecution is done presenting its case at some point this week. No final decision has been made, the source said.
Murdaugh has pleaded not guilty to two counts of murder and two weapons charges in the killings of his wife, Margaret "Maggie" Murdaugh, and son, Paul Murdaugh, on June 7, 2021, at the family's home in Islandton.
Murdaugh contends he called 911 after returning home from a visit to his mother and finding his wife and son dead of gunshot wounds. The South Carolina Attorney General's Office -- which is prosecuting the case because of the Murdaugh family's ties to the local solicitor's office -- has accused the 53-year-old of carrying out the killings to distract attention from a series of alleged financial crimes prosecutors say he was committing.
Separate from the killings, he faces 99 charges stemming from those alleged schemes.
Maggie Murdaugh's sister testifies
Maggie Murdaugh's sister, Marian Proctor, took the stand Tuesday afternoon, offering a comprehensive view of her only sibling and younger sister.
Proctor testified that Murdaugh wanted Maggie to come to Moselle, their hunting property in Islandton, the day of the killings. She said she talked to Maggie, who was staying in the family's Edisto Beach property at the time, and that Maggie didn't want to go. Proctor said it made sense that Alex would need Maggie there because the health of his father, who lived not far from Islandton, had deteriorated.
Proctor broke down as she told the court that she encouraged Maggie to go that day, saying that was the last time that she ever talked to her sister.
She once asked Murdaugh if he had any idea who could have killed her sister and nephew, she said. Alex thought about it and said he didn't know, but "whoever did it had thought about it for a very long time," Proctor testified.
She also said she asked Alex once if he thought they suffered, and he assured her that they did not.
Proctor told the court that after the killings, Murdaugh talked about a 2019 boat crash case involving his son Paul. At the time of his death, Paul was facing charges including boating under the influence and causing the death of 19-year-old Mallory Beach in the crash.
"He said that his No. 1 goal was clearing Paul's name, and I thought it was so strange because my No. 1 goal was to find out who killed my sister and Paul," Proctor said, as her voice began to break.
Under cross-examination, Proctor testified that she wasn't critical of Murdaugh trying to clear Paul's name. She just "thought his priority should have been focusing on finding who killed Maggie and Paul."
"And how do you know that wasn't a priority for him?" defense attorney Jim Griffin asked.
"We never ... talked about finding the person who could have done it. It was just odd. We were sort of living in fear because we thought this horrible person was out there," Proctor said.
When asked about her sister's marriage by the defense, Proctor said: "It was good. It wasn't perfect, but Maggie was happy. She was happy."
Another witness identifies Murdaugh's voice on video
Roger Dale Davis Jr., who twice daily cleaned the Murdaugh's dog kennels, near where the bodies were found, testified earlier Tuesday.
He described the routine, noting that part of cleaning involved hosing the kennels down with a hose that he would then roll up in a coil and hang outside -- carefully, so as to avoid kinks or breaks in the hose.
Davis testified he went to the property twice the day of the murders, as usual -- once in the morning and once that afternoon, around 4:30 p.m. But when shown a photo of the crime scene taken that night, Davis told the court the hose had not been properly stored.
"I'm very particular how I rolled that hose up, and it's kinked up," Davis said of the photo. "If you notice, there's pressure on that hose. Somebody used that hose after I did because it's twisted."
Under cross-examination, Davis acknowledged the hose could be seen on the floor of the kennels in the video Paul filmed the evening of the murders. Paul, Davis testified, was not as meticulous about properly rolling up the hose as he was.
Davis also became the latest witness to identify Alex Murdaugh's voice alongside those of Maggie and Paul in a cell phone video that a law enforcement witness testified Paul filmed in the area of the kennels at 8:44 p.m. that evening, minutes before the state says the murders occurred.
Prosecutors have sought to place Murdaugh at the scene of the killings using the video, contradicting his statements in interviews with law enforcement that he was not at the kennels prior to finding the bodies. Police said he called 911 at 10:07 p.m.
The defense team Tuesday questioned Davis about his perception of the Murdaugh family and Alex Murdaugh in particular. Davis had earlier made comments referring to Alex and his wife as "lovey dovey," he acknowledged, and testified under cross-examination he had never seen Alex Murdaugh raise his voice at Maggie.
Defense attorney Jim Griffin also asked Davis about an instance when one of the dogs was badly injured in the kennels. The decision was made to put the dog down, Griffin said, which Davis agreed with.
"And Mr. Alex couldn't shoot that dog," Griffin said, "and he asked you to do it, didn't he?"
"Yes," Davis said.
Paul's injuries not consistent with a suicide, pathologist says
Earlier Tuesday the court heard the cross-examination of Dr. Ellen Riemer, a pathologist at the Medical University of South Carolina who testified a day earlier about the victims' fatal injuries, during which Murdaugh appeared visibly upset.
Margaret Murdaugh was shot at least four times with an "assault rifle," Riemer said, while Paul Murdaugh was shot twice with a shotgun: The first shot went through part of the left side of his chest and left arm, while the second went through his left shoulder, entered the left side of his neck and head and came out the right side of the top of his head.
Paul's hands were down when he was shot, Riemer testified, telling the court, "I don't see anything on his hands that would indicate he had his hands up to his face in anticipation of the injury that was about to happen," Riemer testified.
During the cross-examination Tuesday, defense attorney Dick Harpootlian pressed Riemer on the possibility that the shot Paul suffered to the head was a contact wound. He cited a book on gunshot wounds highly regarded among pathologists that described injuries resulting from shotgun contact wounds that Riemer acknowledged were similar to Paul's. But she reiterated she did not determine Paul's injuries were contact wounds.
On re-direct, Riemer underscored she did not find soot on Paul's skin as would have been expected from a shot fired from a barrel no further than 6 inches from the wound. She did find stippling on the wound to Paul's chest, she said, indicating a weapon fired at close range with the barrel up to 3 feet away. But
