Singer Jenni Rivera's death has not only brought a wave of gloom among fans but has also raised numerous questions regarding the cause of the crash. According to the Los Angeles Times, Starwood Management, a company that owned the 1969 built Learjet 25 is being pulled up in the case. Due to past instances of the company providing incorrect documentation and fake information it is being speculated if the crash had something to do with false records provided by the company.

In 2005 Starwood Management and a company executive, Christian E. Esquino Nunez, had been in the headlines for providing fake safety records of planes bought from the Mexican government. These planes were sold to private pilots in the U.S. He was accused of conspiring with colleagues to provide false records and wrong documentation of the history of planes. His "fraudulent business practices ... put the flying public at risk," the paper quoted the investigators.

Due to this allegation Nunez was arrested and spent two years in a federal prison in California. On release, he was deported to Mexico. Investigating authorities though haven't mentioned pilot's error or the maintenance of the plane as the cause of the crash yet, these aspects are still being analyzed.

"Obviously my past - there is a story to it," Nunez said speaking to the paper about this speculation. "It's unavoidable that they are going to look at my past.... I think it's fair to bring it up right now and question it."

But he also added that he was sure the plane was maintained with care. "We're all grieving," he said. "I'm definitely very sorry that this happened."

Jenni Rivera's private jet dropped off the radar and crashed nose-first Dec. 9 killing the singer and six other people onboard.
