A man convicted in a 2005 double killing and who is known as the longest-serving jail inmate in Miami-Dade County was finally sentenced Wednesday.

Danyan Mangham, now 43, was convicted just last month for the murders of Robert Berriman and Jorge De Los Rios Jr. 15 years ago.

On Wednesday, Mangham received multiple life sentences during a hearing.

"To have this stretched out so long, the pain doesn't heal," said Robert Berriman's brother, Chuck. "It's like having a wound and you keep peeling off the band aid."

According to records from Miami-Dade County Corrections, Mangham has the longest length of stay in jail. The Miami-Dade State Attorney's Office said he stayed in jail so long because his defense presented mental health incompetency issues during court hearings which delayed Mangham's trial.

"The Miami Dade State Attorney Office never believed that Dayan Mangham was incompetent or mentally ill and when this case was finally able to get before a judge, the jury convicted him," a statement from the State Attorney's Office read, in part.

Danyan Mangham, convicted in a 2005 killing and who is known as the longest-serving jail inmate in Miami-Dade County, will finally be sentenced. NBC 6's Stephanie Bertini reports.

Before Wednesday's hearing, Chuck Berriman vowed to deliver a statement in court.

"I will speak from the heart," he said.

Berriman's mother was still awaiting justice even at her death bed several years ago.

"On her death bed, she made me promise to be there," Chuck Berriman said.
