FT. LAUDERDALE (CBSMiami) – A 20-year old woman who was one of four people inside an SUV when it plunged into a Deerfield Beach lake last week died Sunday evening.

The death of Sandalie Jean-Baptiste came as more than 150 people gathered for a candle light vigil in Pompano Beach park to remember those who died.

Jean-Baptiste had been on life support since the crash.

Thirty seven-year old Nadege Theodore, her 15-year old daughter Lyn and nephew Guivens Daverman, 16, were killed when Theodore’s SUV careened into a lake south of Hillsboro Boulevard after it was involved in a three vehicle crash on the highway Wednesday evening around 10 p.m.

Rescue divers pulled Theodore, Daverman and Jean-Baptiste from the water. Two were found outside the SUV, while the third was inside; all were in cardiac arrest.

The Florida Highway Patrol said they thought they had gotten everyone out, but someone in the family alerted them that was not the case.

“Once we made next of kin notification, one of the family members notified us that there was possibly a fourth person in the car,” said Florida Highway Patrol spokesman Sgt. Mark Wysocky.

Divers went back out to the lake and pulled Lyn’s body from the water Thursday morning.

Family members said Nadege Theodore had just picked the others up at the Boca Town Center Mall and was on the way home to Pompano Beach when the accident happened.

Both teens were sophomores at Blanche Ely High School. Broward Schools Superintendent Robert Runcie and School Board member Nora Rupert took part in Sunday’s vigil.

Basketball star Shaquille O’Neal has offered to help out with funeral expenses.

Classmates of Guivens Daverman remembered him as a promising football player full of optimism.

“We remember he always had a smile, so now we’re down and feel sorry in the tragedy,” said Joseph Johnson. “It’s best we keep a smile on our faces.”

“It’s touching to see how he made us smile. Bad day or good day. That’s the type of kid he was. He always made you smile,” said sophomore Toby Duncan.

A viewing will be held for the victims this Friday at the Paxilla Funeral Home in Oakland Park. All four will be buried on Saturday.
