A South Florida man who was behind the wheel of a car going more than 100 mph when it crashed into a minivan and killed a family of four back in April has been arrested, authorities said.

Paul Wilson Streater, 21, turned himself in Tuesday to face four counts of vehicular homicide, four counts of DUI manslaughter, and three counts of DUI with property damage and/or injury in the April 28 crash, Delray Beach Police said.

According to police, Streater was driving his 2010 Chevy Silverado at more than 100 mph when he rear-ended the Dodge Caravan on South Federal Highway near Lamat Avenue.

The driver of the van, 50-year-old Jorge Raschiotto of Argentina, his sister, 42-year-old Victoria Raschiotto of Mexico, and her two children, Diego, age 8, and Mia, age 6, were all killed in the crash. The family was on vacation and was returning to a rental home after a day at the beach.

"Witnesses described a collision so violent it sounded like an explosion," police said in a statement. "When the crash happened, the rear of the pickup became airborne and then embedded in the van as the two vehicles continued southbound across the northbound lanes of Federal Highway for almost 250 feet."

Police said toxicology tests on Streater's blood later showed the presence of Difluoroethane, the main ingredient in Dust-off, a brand name of canned air commonly used to remove dust from electronics equipment. The product is commonly abused by people who inhale it to produce mind-altering effects, also known as "huffing."

In Streater's truck was a receipt from Walmart showing the purchase of two cans of Dust-off on the afternoon of the crash, police said. Video from the store showed Streater and his passenger buying the cans at the store hours before the crash, police said.

Streater, who police say is from Fort Lauderdale but has a Delray Beach address listed in jail records, remained behind bars Wednesday. Attorney information wasn't available.
