After his guilty verdict on Friday on a lesser charge of manslaughter for the 2019 death of his wife, Andre McDonald, a Jamaican-born US Air Force Major, was sentenced to the maximum sentence of 20 years in prison on Monday.

The sentence was read by presiding judge ,Judge Frank Castro. McDonald will be eligible for parole after 10 years.

McDonald, 40, is the son of Portland businessman Everton "Beachy Stout" McDonald who is accused of murdering both his wives in Jamaica. “Beachy Stout” is currently in custody and is scheduled to stand trial in September for the murder of his second wife.

McDonald was originally charged with the murder of his wife Andreen McDonald, which carries a maximum penalty of a life sentence.

His guilty verdict came after deliberations ensued for 12-and-a-half hours and an "Allen Charge' read by the judge, which is intended to put further pressure on the jury to come to a unanimous decision. If not, Castro could have declared a mistrial.

During last week's testimony, it was reported that he confessed to killing Andreen and disposing of her body in 2019, but said he acted in self-defence.

The verdict comes nearly four years after McDonald's disappearance, which led to months of searching across Bexar County.

Pam Allen, the leader for Eagles Flight Advocacy and Outreach, has been helping the family since Andreen went missing in 2019. She sat in the courtroom alongside the family and said she’s disappointed with the verdict, Kens5 reported, adding that Allen said the family is trying to remain strong for the couple’s 11-year-old daughter.
