Families of Victims in Jenni Rivera Plane Crash Prep for Battle

The families of Jenni Rivera's entourage members killed in her plane crash are tired of waiting for the multimillion dollar judgment they were awarded, so they've called in the big guns to collect.

We're told 7 family members of Jenni's publicist, makeup artist, hairstylist and lawyer have retained a firm to get the $70 million Starwood Management -- owners of the doomed Learjet -- was ordered to pay 2 months ago.

Attorney Danny Abir tells us his firm plans to go after Starwood assets, which include at least two airplanes.

Abir's firm is the one that already squeezed one settlement out of Tyga -- and is currently working on another.
