Earlier this week, the comedy world was stunned by the passing of Kevin Barnett.
The highly-respected comic and co-creator of the Fox series Rel was just 32 at the time of his death.
Details of Barnett's final hours remain scarce, but it's now been confirmed pancreatitis was the comedian's cause of death.
Barnett was vacationing in Mexico at the time of his passing.
"We can confirm the death of a U.S. citizen, Kevin Barnett, in Tijuana on Jan. 22," a U.S. Department of State official told E! News in a statement issued on Thursday.
"We offer our sincerest condolences to his family on their loss, and we stand ready to provide all appropriate consular assistance. Out of respect to the family during this difficult time, we have no further comment.
"The corresponding autopsy was carried out, which determined that the cause of death was: Non Traumatic Hemorrhage, caused by pancreatitis," the statement reads.
"At the moment his body is still in facilities of the Forensic Medical Service of Tijuana, waiting to be delivered to his family members who are performing the legal proceedings."
Barnett's final social media post indicated that he was in Mexico, but did not suggest that he was aware of any issues with his health.
"In mexico. Bought myself a sweater," he captioned the post.
"Been accused of appropriation several times. In my head I just gave a lady some money so I ain't cold. Either way. Swag heavy. Mixtape comin."
On social media, Barnett's friends and fellow comics have been paying heartfelt tribute to the young up-and-comer.
"i am so sad," tweeted Brooklyn 99 star Chelsea Peretti.
"Kevin Barnett was an incredible comedian and writer, contributing to Broad City, the stand-up community and beyond," Comedy Central tweeted Tuesday.
"He'll be greatly missed."
In addition to his work on Rel, Barnett contributed to numerous television shows and movies, including Broad City, The Carmichael Show and The Heartbreak Kid.
A celebration of Barnett's life hosted by several of his fellow comedians will be held at The Bell House in Brooklyn this evening.
