Chuckles, hugs and tears filled Smith-Wilemon Park on Sunday evening as dozens of people gathered for a candlelight vigil to remember three teens described as devoted friends who were killed in a fiery crash early Saturday in Arlington.

Friends and relatives passed along story after story about Jacob Ramos, 17; Charles Lavering, 19; and Colton Goodman, 18, who lived just across the street from the park in east Fort Worth.

But Monica Elliott, Goodman's girlfriend, took a brief moment to warn the many young people there about the dangers of driving.

"You must be very careful," Elliott said as she quietly sobbed. "You're not invincible."

Lavering was driving a BMW sedan north on West Green Oaks Boulevard just south of Arkansas Lane in Arlington about 1:20 a.m. Saturday when he apparently lost control of it at Firewood Drive.

The car hit a curb, veered across the northbound and southbound lanes, jumped another curb and smashed into a collection of AT&T cellular boxes and an electrical pole before flipping and catching fire, Arlington police have said.

A fourth teen crawled out of the car and survived.

The other teens were trapped in the car before Arlington firefighters pulled them out. They were taken to Parkland Memorial Hospital in Dallas, where they died of burns.

Arlington police have said they believe that high speed was involved.

Investigators are awaiting toxicology results, Arlington police Sgt. Christopher Cook said Sunday. He said results could take some time.

Police will conduct a full reconstruction of the crash in a few days.

Friends and relatives said the teens cherished their cars.

Lavering's prize possession was his BMW.

"He loved that car," cousin Ray Guillen said Saturday.

And Goodman loved his Civic EG hatchback.

That car sat parked in front of his Fort Worth home, across the street from the park where the vigil was held.

Daisies lay on its hood, and someone had written the words in white shoe polish, "We miss you Colty" on one of the windows.

"He was quiet when you first met him," said Jerra D. Merritt-Henderson, who had known Goodman for 10 years. "But once he got to know you, he was always giggling and funny."

Elliott told the crowd that Goodman and his pals were almost inseparable.

"We all are going to miss him," she said of her boyfriend. "And we're going to always remember all of them."
