A former U.S. Navy man responsible for the mysterious disappearance and killing of his wife in San Diego more than 6 years ago learned Friday he would spend more than a decade in prison for the crime.
Matthew Sullivan, now 36, was sentenced to 16 years to life in prison for second-degree murder in the stabbing of his wife, Elizabeth Sullivan, 32. She was the mother of the couple's two daughters.
Before learning his fate, a masked Matthew Sullivan sat expressionless while friends and family spoke about his wife who "was loved by many."

This sentence will do nothing to fix that [she's gone], however, it may help pack the chasm left behind by the demonic act of Matthew Sullivan," said Elizabeth Sullivan's godsister Calandra Duckett.
Elizabeth Sullivan's friend, Nathan Caracter, spoke directly to Matthew Sullivan when he said that his wife did not hate him.

"This man killed my dear friend and you can imagine how this affected me," Caracter said. "But a longer sentence won’t make the pain go away, nor will my recanting of sorrow I have gone through these past six years make this man feel differently than he does now.”
Matthew Sullivan decided to make his own statement, but did not address the crime he's accused of or his wife and instead chose to call out what he felt were problems with his trial.
"The only issue I had about trial was I believe I was not allowed to call in relevant witnesses to my defense," he said. "I thoroughly believe their testimony would've thoroughly changed the verdict in this trial."
The prosecutor harshly criticized Matthew Sullivan's statement as she asked a judge to sentence him to 16 years to life in prison without the possibility of probation.
"There is clearly no remorse from the defendant," the prosecutor said. "He thinks he could've gotten a different verdict apparently. He doesn't feel one iota of sorrow for what he did. He does not deserve probation."
The judge agreed with prosecutors.
"The jury verdict and the evidence at trial makes clear that Matthew Sullivan brutally murdered his wife, methodically cleaned up the messy murder site and then hid the body for years. He almost got away with it but his final attempt to hide the body at the bottom of the bay failed," the judge said before handing down his sentence.
Matthew Sullivan has the right to appeal his trial.
The case of the Sullivans first gripped San Diego six years ago – in October 2014 – when Elizabeth Sullivan suddenly vanished. Nearly two years to the date of her disappearance, her decomposing body was found floating in San Diego Bay, about a half-mile from the home the couple once shared with their daughters. She had been stabbed to death.
Matthew Sullivan was identified as the suspect in his wife’s slaying. He was arrested in late January 2018 at his home in Delaware and extradited to San Diego. He was booked into jail on Feb. 9, 2018.
His trial began on Feb. 21, 2020, and, in March, a jury found him guilty of Elizabeth Sullivan’s murder.
The Disappearance & Killing of Elizabeth Sullivan
Elizabeth Sullivan was reported missing on Oct. 14, 2014.
She was last seen one day earlier near San Diego’s Liberty Station, where she lived with her family. A text message sent on Oct. 13, 2014, was the last contact Elizabeth Sullivan had with loved ones before her phone was turned off.
San Diego police searched for the missing Navy wife and mother for two years, to no avail. Day by day, week by week, the case grew cold as her family pleaded for her safe return.
But a grim breakthrough came on Oct. 6, 2016.
That day – nearly two years after she vanished – the body of Elizabeth Sullivan was found floating in San Diego Bay, near her home. It was also the same day Matthew Sullivan was moving from San Diego to Maryland with his new girlfriend, a fact that prosecutors said was no coincidence.
Due to the decomposition of Elizabeth Sullivan’s body, it would be another week before SDPD investigators would be able to positively identify her – and another year-and-a-half before police could link Sullivan to her killing.
The San Diego District Attorney's Office believes Elizabeth Sullivan's body had been “hidden somewhere” before it was disposed of in the bay.
Matthew Sullivan was arrested outside his home in Wyoming, Delaware, on Jan. 31, 2018. He was extradited to San Diego and eventually booked into the George Bailey Detention Facility in early February, where he remained until he could face his first-degree murder charge.
Significant court proceedings began one year later, with Matthew Sullivan’s preliminary hearing in February 2019. As details of Elizabeth Sullivan’s disappearance and death emerged, a judge ruled Matthew Sullivan would stand trial for her murder.
The Murder Trial
Matthew Sullivan’s murder trial began on Feb. 21, 2020, with opening statements and testimony from the loved ones of Elizabeth Sullivan.
On that first day of trial, Matthew Sullivan sat silently, looking down at the desk in front of him as Deputy District Attorney Jill Lindberg described how his “whirlwind romance” with the victim quickly turned to domestic violence, and eventually, murder.
A potential motive, according to prosecutors during opening statements, was an extra-marital affair that Elizabeth Sullivan was having, and that Matthew Sullivan learned of about a month before his wife’s disappearance.
“He had lots of motives, he had the means, he had the opportunity,” Lindberg said. “The crime scene was in her bedroom. The murder weapon was in the attic over his bedroom.”
Lindberg showed jurors the knife that Matthew Sullivan used to stab his wife. She said he stabbed her at least five times, hitting several ribs and leaving a pool of blood on the floor of Elizabeth Sullivan’s bedroom.
The murder weapon was found in the attic of the home the couple shared in the Liberty Station area, after Matthew Sullivan moved out.
Matthew Sullivan’s defense attorney, Marcus Dubose, painted the defendant as a man attempting to hold on to a wife that was pulling away, turning towards a self-destructive lifestyle.
Dubose argued that blood found in Elizabeth Sullivan's bedroom was from a wound that the Navy wife inflicted on herself during a tumultuous time in the couple's lives. According to police reports obtained by NBC 7, there was a history of domestic violence in the couple’s marriage and they had been arguing over custody of their two young daughters and child support.
