A Miami-based Canadian diplomat issued a statement Thursday after her teenage son and another man were killed and her younger son was arrested following an alleged drug deal that turned into a gun battle.

Consul general Roxanne Dube and her family expressed condolences to the family of Joshua Wright, the other deceased victim, and said they just want to be there for the younger son.

Dube's ex-husband and the boy's father, Germano Wabafiyebazu, has said 17-year-old son, Jean, was killed when he went into a house to buy marijuana Monday, and that police arrested his 15-year-old son, Marc Wabafiyebazu.

Germano Wabafiyebazu said his sons borrowed their mother's personal car, which has diplomatic license plates, to drive to the house but told their mother they were just going for a drive. He said he was told that Marc rushed into the house after hearing a gunshot.

Dube thanked people for their messages of support in in the statement before addressing's Wright's family.

"Your grief is our grief," she said. "We can only hope that, in time, we will find common purpose towards diminishing the causes of such violent crimes. For now, we just want to be there for Marc, our incredibly caring son who loved his brother very much, and to say goodbye, ever so tenderly and quietly to Jean, our love."

The Miami Police Department has not commented on the shootings. The Miami-Dade State Attorney's Office confirmed that another man, 19-year-old Anthony Rodriguez, was charged with second-degree murder and marijuana possession with intent to sell for his alleged role. The Rodriguez arrest report says a second man was shot to death inside the house. Prosecutors also said Rodriguez was wounded in the arm in the shootout.

The police report also quotes unidentified witnesses as saying Rodriguez brought two pounds of marijuana to the house and began to negotiate.

"During the negotiations, both deceased victims became involved in an exchange of gunfire," the report says.

In addition, Marc Wabafiyebazu faces charges of threatening a police officer while in custody, according to a separate police report. The boy is alleged to have said "he was going to kill (a detective) and that he would shoot him in the head."

It was not clear whether Marc Wabafiyebazu would be charged as a juvenile or an adult but he is due in juvenile court on April 8.

Authorities say he would not be protected by diplomatic immunity.

Germano Wabafiyebazu said he and Dube were divorced a few years ago and that their son Jean struggled with substance abuse.

Dube just started her job as consul general in Miami in February. She was previously Canada's ambassador to Zimbabwe from 2005 to 2008 and also served as a staff member for a Canadian Liberal cabinet minister for more than a decade.

John Babcock, a spokesman for Canada's foreign department, said Louise Leger has been named acting Head of Mission on an interim basis.
