ST. PETE BEACH – Pinellas County Sheriff deputies arrested a suspect Tuesday in connection to a car crash near the Alden Beach Resort that killed two people.

Daniel Dalton Dolcater, 20, of St. Petersburg was arrested in the accident that killed Pablo Alonso Mansilla-Aguinaga, 32, from Tampa and Sandra Paulson, 33, from Schaumberg, Ill.

Dolcater faces two counts of DUI Manslaughter, a single count of Aggravated Fleeing and Eluding, and one count of Driving While License Suspended Causing Death. He is being held on $101,000 bond.

The Sept. 30 accident happened in the 5900 block of Gulf Boulevard of St. Pete Beach. Invesitgators believe that the suspect’s car may have been involved in a high-speed chase or race prior to the crash.

Police had clocked Dolcater at 69 mph in a 35 mph zone. He was driving south on Gulf Boulevard and sped up when police attempted to stop him.

Dolcater’s car collided with the 2006 Silver Mazda 3 SUV carrying Mansilla-Aguinaga and Paulson.

The accident threw the SUV into the fountain in front of the Alden Beach Resort. The two victims died at the scene.

Dolcater was ejected from his Silver GMC Yukon SUV and was found lying unconscious in the street. He was transported to Bayfront Medical Center, where he was released Tuesday, at which time he was arrested.

On Oct. 2, the Pinellas County Sheriff’s Office Major Accident Investigation Team (MIAT) took over the investigation at the request of the City of St. Pete Beach. Investigators have been working closely with St. Pete Beach Police to reconstruct the events surrounding the crash.

As part of the investigation, deputies are asking the public’s help to identify another vehicle that was  seen with Dolcater just prior to the deadly crash.

Deputies say witnesses saw Dolcater racing or chasing another vehicle in the area of Fifth Avenue and 66 St. North in St. Petersburg.

The second vehicle was described as an older model maroon or purple minivan. No driver or occupants were seen. The driver of this vehicle may have additional information related to the crash.

Anyone with information, either about the minivan, or about the accident, is asked to call Pinellas County Sheriff’s Office Investigator Corporal Nicholas Lazaris at 727-582-6200.
