Las Vegas, NV (KTNV) -- New information has been released on the fatal crash on Summerlin Parkway near Rampart on Wednesday evening.
Authorities have identified both the man and woman killed in the wreck as 20-year-old Savanna Gonzales and 31-year-old Frank Spenia III.
Both families are grieving the loss of the young couple hit and killed by a truck head-on; the truck crossed over the center median into oncoming traffic.
NHP said the driver of the truck may have been under the influence at the time of the crash.
Savanna's family said she was picking up her boyfriend, Frank, from work and they were on their way home when the crash happened.
"Two innocent people just driving home and a drunk driver just flew across, just this freak accident happened, he just slammed them. I feel it could have been prevented," said Jessica Bustamante, victim's sister.
Bustamante said the couple had been dating for about a year. After graduating, Savanna was ready to start nursing school.
She said their deaths are raising more questions about the median on Summerlin Parkway.
"It does serve its purpose. The rocks do slow the cars down, you have the bushes, you have the trees, which serve as that barrier. They keep vehicles from traveling over," said NHP Trooper Loy Hixon.
But some say the rocks aren't enough, and a guardrail is the only way to prevent crashes.
"There needs to be something put there so this doesn't happen again," said Bustamante.
The city said it will conduct a traffic study in the area.
The driver of the truck was hospitalized in critical condition. NHP said he will face charges in the couple's death.
Savanna's family and friends will be holding a vigil in her honor. It's set for Friday, Feb. 7 at Arbor's Tennis & Play Park in Summerlin at 7:30 p.m.
The family has also set up a donation account, to help with funeral expenses.
