The court “will notify (Paddock’s) family members, and we’ll see where this goes,” lawyer Richard Patterson, representing Phippen’s son Travis, told CNN.
“We want (Paddock’s estate) administered by the court. I don’t think we’re at the bottom of (Paddock’s assets),” Patterson said.
Phippen was killed when gunman Stephen Paddock rained down bullets into the crowd at the Route 91 Harvest Festival from his suite in the Mandalay Bay Resort and Casino.
Paddock, a 64-year-old retired accountant, used modified assault rifles to fire hundreds of rounds into the panicked crowds.
Investigators are still trying to piece together what drove the wealthy high-stakes gambler who owned two planes and homes in four states to amass an arsenal of weapons and open fire from his 32nd-floor room last Sunday.
Clark County Undersheriff Kevin McMahill said investigators had “looked at literally everything” and still do not have a clear motive.
Paddock’s brother said the gunman made at least $2 million when the two sold their real estate business a few years ago.
And just before the massacre, he wired $100,000 to his girlfriend, Marilou Danley, in the Philippines before killing nearly 60 people and taking his own life.
Vice President Pence visited Las Vegas Saturday, delivering a speech following a prayer walk.
“May God bless the fallen, the injured, and their precious families. And may God bless America,” Pence said.
A GoFundMe page for Phippen raised more than $62,000 by Saturday.
