FORT STEWART, Ga. (AP) -- An Army soldier accused of strangling his pregnant wife so he could pocket $500,000 in benefit money was convicted Thursday by a military judge in a case that hinged on dueling medical experts who couldn't agree on how the woman died.
Pvt. Isaac Aguigui, 22, of Cashmere, Wash., was sentenced to life in prison with no chance of parole at the end of his four day court-martial at Fort Stewart. A military judge found him guilty of murder and causing the death of an unborn child. His wife, 24-year-old Sgt. Deirdre Aguigui of Minneapolis, was about seven months pregnant when she was found dead in their apartment on July 17, 2011.
The verdict should have little impact on Isaac Aguigui's overall fate. He's already serving life without parole at a Georgia prison after pleading guilty last summer to murder charges in a double slaying that occurred nearly five months after his wife died. Parents on both sides of the case said the tragedy cost them three lives -- the convicted husband, his slain wife and the grandchild who was never born.
"I don't know what happened to my son," Annette Aguigui, the defendant's mother, said as she and her husband left the courthouse in tears. "... I am angry, I am disappointed, I am broken beyond broken. But I can't stop loving my kid."
Alma Wetzker, Deirdre Aguigui's father, had urged his daughter to consider leaving her husband when she called angry and afraid two days before her death.
"I was proud to call him him my son-in-law," Wetzker said. "I'm not sure exactly what caused the downfall. I have no anger toward him. And, for me, I freely forgive him for everything."
Isaac and Deirdre Aguigui met at a military prep school in 2009 and were married months later. But friends testified that by the summer of 2011, their marriage had been strained by his drug use and infidelities by both spouses. Friends said Isaac Aguigui doubted the child his wife carried was his and he wanted a divorce.
Prosecutors had no problem presenting a motive. Weeks after his wife died, Aguigui received $500,000 in life insurance money and military death benefits. Evidence showed that hours before his wife died, Aguigui sent a text message to a former girlfriend: "We'll have plenty of money. All need is your body whenever I want it."
But evidence of what specifically killed Deirdre Aguigui proved scant. The military's autopsy found more than 20 bruises and scrapes on the body including on her head and back, none fatal. Wounds on both wrists appeared to match a pair of handcuffs found on the couple's bed. But an official cause of death was not determined. The military couldn't decide whether she had been slain or died from natural causes.
Last year, a Georgia state medical examiner offered a second opinion. By ruling out illnesses, drugs or poisons, allergic reactions and other potential causes -- and by noting the wrist wounds and other injuries -- Dr. James Downs concluded Deirdre Aguigui was strangled while struggling violently against handcuffs behind her back. He said a certain chokehold taught to soldiers could kill while leaving few if any telltale marks.
"That's why this is such a great way to kill someone if you want to get away with it," Army prosecutor Janae Lepir said in her closing argument Thursday. "You put this hold on someone and it could leave almost no finding."
Defense lawyers noted in closing arguments that the military medical examiner and three other specialists involved in the autopsy couldn't find a decisive cause of death as Downs had. Another medical expert called by the defense said it was more likely Deirdre Aguigui suffered a sudden heart attack, though prosecutors insisted his diagnosis was based on a faulty reading of her medical history.
"All the government has presented here today is one man's theory that is no more possible than any other possibility that no other doctor could rule out," said Capt. Scott Noto, one of Aguigui's Army defense lawyers.
Aguigui didn't testify. The defense's only witness was its medical expert.
A former Army buddy, Michael Schaefer, testified that a month after his wife's death, Aguigui gloated that he had handcuffed her during sex and strangled her with a plastic bag over her head. Defense attorneys noted that Schaefer, who had spoken to Army investigators and testified previously at a pre-trial hearing, had never before mentioned a confession.
