Jamaican American reggae artist Jo Mersa was reportedly found unresponsive in a vehicle in the US earlier this morning, with South Florida radio station WZPP claiming to have confirmed that he unexpectedly died from a heart attack

Jamaican-American reggae artist Joseph Mersa-Marley died on Tuesday at the age of 31.

The musician was found unresponsive in a vehicle in the United States on Tuesday, according to the streaming service TIDAL.

The artist – who went by his stage name Jo Mersa – reportedly had suffered from asthma his entire life and the Florida radio station WZPP claimed he had died of an asthma attack, Daily Mail reports.

He was the grandson of iconic reggae musician Bob Marley and the son of Stephen Marley.

Bob tragically died of cancer in 1981 at the age of 36, but he is widely considered one of the pioneers of reggae music. The late star had 11 children with seven different partners.

Daily Mail notes that it has reached out to Joseph’s representatives for comment.

His representative confirmed his death to Rolling Stone on Tuesday but a cause of death was not immediately disclosed.

Prime Minister of Jamaica Andrew Holness shared news of Marley's death on Twitter Tuesday, offering "heartfelt sympathies" to friends and fans.

"His untimely passing at the young age of 31y.o. is a huge loss to the music as we look to the next generation," Holness tweeted.

He recently spoke about his grandfather's legacy in an interview with Reggaeville. 

We always hear those reflections, speaking about those things, about the role that he played not only as family member and father, but also in the world and the impact he had on the Reggae community and the Reggae culture, the roots, bringing forward the message of Rastafari and love, over all love," he shared. 

Marley spent his early years in Jamaica, where he attended Saints Peter and Paul Preparatory School. He then moved to Florida where he was a student at Palmetto High School. When at Miami Dade College he studied studio engineering.
