ST. LUCIE COUNTY — The Florida Highway Patrol identified Wednesday four of the five killed last week in a fiery wreck, the deadliest on the Treasure Coast in recent memory.

Investigators also disclosed there was a sixth person, a 14-year-old girl, in the 2002 Dodge Dakota pickup that caught fire in the Friday crash. She survived.

Four of the five who died were identified as Fort Pierce residents Anthony Victor, 21; Anthony Martin, 16; and Alexis Chaney, 17; and Darien Douglas, 21, of Port St. Lucie.

FHP officials continue to work to notify family members of the death of the driver of the Dakota. That person's name was not released.

The crash happened about 10:41 p.m. as three vehicles drove south on South 25th Street, approaching Midway Road, state troopers said.

Tanner Ray Dashner, 21, of Fort Pierce, drove a 2004 GMC Yukon SUV approaching the Dakota and a 2003 BMW 325i at the intersection. He was going faster than the pickup and car, according to FHP.

The SUV slammed into the Dakota, causing the pickup to crash into the BMW in front of it.

State troopers said the Dakota burst into flames, killing five inside.

Lt. Alvaro Feola, FHP spokesman, said another person in the Dakota, 14-year-old Ari'yonnia Stanberry, of Fort Pierce, was pulled out of the truck by a bystander.

Stanberry was listed as a front right passenger. Feola said she was hospitalized overnight and released in the morning.

Dashner remained listed in critical condition Tuesday. The driver of the BMW was not hurt, while a passenger suffered only minor injuries.

Feola said troopers are closely inspecting the vehicles involved, the damage sustained and the scene itself to get a better understanding of exactly what occurred.

"It's a complex investigation. It takes time," Feola said. "We'll gather all the information from the scene and from the vehicles."

"Things like this take time," reiterated Assistant State Attorney Brandon White, the prosecutor assigned to the case.

Investigators are still looking for witnesses. If you have information about the crash, call the State Attorney's Office at 772-465-3000 and ask for Ed Arens.

Two fundraisers to benefit the victims' families, both complete with food, drinks and music, are scheduled for Sunday in Fort Pierce:

3-7 p.m.: Woodfyah Bar and Grill, 2164 U.S. 1

4-8 p.m.: Raziyah Caribbean Cuisine, 214 N. 25th St. Proceeds from the next-door Hot Spot Car Wash & Auto Detailing also will go to the families during these hours.

Anthony Victor, 'really great person'

Tatyana Roberts, 19, said she was a close friend of Anthony Victor, describing him as "just a really great person."

"On Thanksgiving, I was with him and we were talking about my problems," Roberts said. "He never wants to see me down or sad. He'll always uplift me and motivate me and tell me, 'Oh, you're too pretty to be sad or stressing.'"

Roberts said Victor went to Fort Pierce Central High School and said he and his friends made music. In music, she said Victor went by the name "Jimmy Mack."

She said they met on Facebook and hung out.

"Something that really stood out to me about Anthony is his big personality," Roberts said. "He was always joking around and smiling."

She said she communicated with Victor an hour or so before the crash via FaceTime. She said they had just left Walmart on Okeechobee Road, but she didn’t know where they were going.

Roberts said she recently got out of basic training in the Army.

"I'm glad I got to see him while I did," she said.

Esther Simon, 20, this week came to the crash scene where dozens of candles crowded the sidewalk. She said she knew Victor from high school and met him through a friend.

"He was a sweetheart," Simon said. "We used to go to the fair together, out to eat, hang out while we were bored."

Alexis Chaney helped children

According to Fort Pierce police, Chaney volunteered at First Step Park on Tuesdays "to help feed and uplift the lives of the younger children in the community.”

Fort Pierce police paused in memory of Chaney, known as "Let Let," at a Courageous Kids gathering Tuesday night. Courageous Kids is a community outreach program.

The kids raised blue glow sticks in the air during a prayer, police said, noting blue was her favorite color.

Police Chief Diane Hobley-Burney and Deputy Chief Kenny Norris encouraged the youths and adults to work to be their best.

Anthony Martin enjoyed bowling

Martin spent at least every Tuesday and Saturday at the bowling alley, but would sometimes show up every day of the week.

"He wanted to go take up bowling after graduating," grandmother Nancy Yearby said.

He made the all-area first team as a freshman and had an 817 three-game series in 2017. Reaching 800 in three sets is considered one of the most difficult and prestigious accomplishments in the sport.

"He truly loved being here," said Midge McArdle, youth director at Saint Lucie Lanes. "It's a tight-knit group. We're family."

Darien 'Hatch' Douglas had ‘positive personality’

Julien Simeus, 20, said he was close friends with Douglas, known as “Hatch.” Simeus attended Fort Pierce Central High School with Douglas.

“We just became close since then,” Simeus said.

Simeus, who also said he is a cousin of Victor, described Douglas as “very laid back, very chill.” He said Douglas was quiet if he didn’t know you.

“He had a positive personality,” Simeus said. “He never really tried to be down.”

He said Douglas had a brother and sister and was involved in air-conditioning work.

“He was really just trying to get himself together, get back on the right track,” Simeus said.

Simeus said he was in a traffic crash in March 2017 and that Douglas supported him in the hospital as he got better. That, he said, is his fondest memory of Douglas.

“When I was at my weakest point … fighting for my life, he was actually there to assist me and help me recuperate and get back on my feet,” Simeus said. “It’s just crazy that this happened and I can’t even return the favor.”

Friends or family of the others involved in the crash could not be reached.
