Tito Jackson, member of the Jackson 5, passed away after being rushed to a hospital in New Mexico due to a heart attack, according to reports.

Terry Harvey Maltbia, described as a close friend and business partner of Jackson, has shared details about the singer's last moments with the Daily Mail.

Maltbia stated that he, Jackson, and their friend Ronald Balfour were traveling from Oklahoma to California to collect some of Jackson's classic cars when they stopped in New Mexico after Jackson complained of feeling unwell and having difficulty breathing.

According to Maltbia, they arrived in New Mexico around 6 PM on September 15 and decided to eat before continuing their drive back to Jackson's ranch in Claremore, Oklahoma.

Speaking to the Daily Mail, Maltbia revealed, "We just got done eating turkey and chicken, laughing and talking."

He continued, "We were putting the top on the convertible because it started raining. That's when Tito came back on the passenger side window and said, 'My chest is hurting. Can you help Ronnie to finish the [car] top?'"

"[Tito] said, 'I ain't feeling good in my chest.' He wiped his face off, took off his shirt and it was like someone had threw a bucket of water on him."

Maltbia urgently called nearby police for assistance, leading them to call for an ambulance swiftly.

The Jackson 5 member maintained his composure as he was wheeled into the emergency room, even talking with his companions and requesting that they retrieve his insurance card from his bag.

"I figured everything was going to be OK since we got him to the hospital and he was still talking."
