 A used car salesman was killed when a red Corvette crashed during a test drive in Ontario, and the prospective car buyer was arrested on suspicion of vehicular manslaughter Tuesday afternoon, police said. 
 
 A fatal crash occurred about 12:45 p.m. near the CarMax at 4100 Inland Empire Blvd., Sgt. Jeff Higbee of the Ontario Police Department confirmed to KTLA. 
 
 A 28-year-old from Union City, Alex Demetro, was driving the vehicle when the car struck a tree, killing the 43-year-old male passenger, the salesman, Higbee said. 
 
 Witnesses said the Chevrolet Corvette was being driven at a high rate of speed, and the driver lost control before crashing into a tree, a police news release stated. 
 
 Several people who witnessed the crash -- on Mercedes Lane south of Councours Street, a couple blocks from the CarMax -- told KTLA the Corvette was going at least 70 mph. 
 
 Demetro was arrested on suspicion of vehicular manslaughter and felony driving under the influence of drugs. Police did not say if he was injured. 
 
 The suspect was not believed to have been under the influence of alcohol, but investigators were looking at whether drugs were a contributing factor, Higbee said. 
 
 The victim, identified by co-workers as 43-year-old Warren Smale, was transported in critical condition to San Antonio Regional Hospital, where he died. 
 
 "It's a part of our job, the test drives," co-worker Lydia Garrett said. "I know Warren ... he probably had no clue, I'm sure." 
 
 A number of co-workers gathered at the crash site Tuesday night, where they remembered Smale as fun-loving and full of life. 
 
 "He was the guy at work that it didn't matter what kind of day you were having, he was there for you," Garrett said. "He would make you laugh. He would make you smile." 
 
 Kerissa Schartner heard the crash and went outside, where she saw Smale still in the passenger seat and Demetro sitting on the ground holding his shoulder. 
 
 "I think he was probably shocked," Kerissa Schartner said. 
 
 Cellphone video from a witness showed the victim being removed from the car. 
 
 Broken glass and debris was left at the scene Tuesday evening, and the tree that the Corvette struck had deep gouges in its bark. 
 
 "It kind of made me realize life is very fragile," said witness Paul Romo. "That guy had no idea today would be his last day when he showed up to work today." 
 
 CarMax spokeswoman Catherine Gryp issued a statement calling the loss "an incredibly sad day for the CarMax family." 
 
 "Our hearts and prayers go out to our associate's family. CarMax is working closely with the authorities on the investigation," the statement read.

 A San Jacinto family is mourning a 29-year-old mother of three, who died along with her unborn child after colliding head-on with a suspected DUI driver over the weekend. 
 
 Krystil Kincaid was driving her Chrysler minivan north on Warren Road around 8:30 p.m. Sunday when a BMW heading southbound veered into her lane and struck her between Devonshire and Esplanade avenues in Hemet, according to Hemet police. 
 
 The blue BMW had been driving at a high rate of speed, investigators said. 
 
 Officials who responded to 911 reports of the crash found the silver van was partially on fire. After firefighters put out the flames, first responders had to extricate Kincaid — who was eight months pregnant — from her vehicle, police said. 
 
 Both Kincaid's legs had become pinned underneath her dashboard due to the extensive damage her car sustained, according to a GoFundMe page created to raise funds for her memorial costs. 
 
 Her husband of 12 years, Zach Kincaid, told KTLA she had him on speakerphone as the crash occurred. 
 
 He said he could hear her scream before impact, then the sound of metal and firefighters using the jaws of life as they tried to pull her from the wreckage. It's a memory that will haunt him, he said. 
 
 Krystil was flown by helicopter to a nearby trauma center, and officials had originally said she was expected to survive. 
 
 But according to Zach, she and her unborn child were legally dead as of Tuesday. Krystil remained on a breathing device only so that her organs could be harvested for donation, he said. 
 
 She leaves behind an 11-year-old daughter, two sons ages 8 and 4 and a 14-year-old stepchild. 
 
 Zach wrote on his Facebook page that sharing the traumatic news with his children was "the hardest thing i have ever done." 
 
 "I told my 2 daughters and my 2 sons that a drunk driver killed their mom," he wrote. "The pain and anger I feel within my soul is immeasurable, my heart is broken. Until we meet again Raven…" 
 
 In an interview with KTLA, he said the children had gone to the hospital expecting to welcome a new family member. 
 
 “They thought they had a baby sister here," Zach said. "They got the worst news of their life. They were told that they don’t have a mom, or a baby sister, anymore.” 
 
 Police said they found the BMW driver, identified as 28-year-old Burbank resident Marcos Forestal, walking near his wrecked car. 
 
 Forestal, a native of Cuba, is the reigning World Boxing Federation International Super Bantamweight champion. 
 
 According to El Nuevo Herald, a Spanish-language newspaper in southeast Florida, Forestal livestreamed the aftermath of the crash as first responders were arriving. 
 
 "Guys a car appeared and I had an accident," the man identified as Forestal is heard saying as he videos the mangled remains of his BMW. "Look at what happened to me, gentlemen. A car came out in front of me and look and what happened to my car." 
 
 Forestal showed signs of alcohol intoxication and was arrested on suspicion of driving while intoxicated and causing a collision that resulted in major injuries, officials said. 
 
 But after Kincaid and her fetus died, the arrest charge was upgraded to gross vehicular manslaughter while intoxicated, inmate records indicate. 
 
 The suspect was also treated for minor injuries at a local hospital before being taken to the Riverside County Jail. 
 
 Forestal was being held on $75,000 bail, according to inmate records. 
 
 The boxer's manager, Christina Carrillo at JAB Management, said in a statement emailed to KTLA: "I would like to extend my deepest condolences to those that have lost their loved ones in this horrible tragedy. At this time, we are cooperating fully with the ongoing investigation." 
 
 As of Tuesday night, Kincaid's GoFundMe campaign had raised more than $18,000 of its $20,000 goal.

– It was just another test drive—a regular task in the daily routine of a used-car salesman. But for CarMax's Warren Smale, it turned out to be his last ride after a potential buyer crashed the red Corvette they were driving in Tuesday into a tree, killing the 43-year-old salesman in Ontario, Calif., and ending in the driver's arrest, the Los Angeles Times reports. Alex Demetro, 28, was charged with vehicular manslaughter and driving under the influence of drugs after witnesses say he lost control of the car, the Ontario Police Department tells KTLA. The Corvette was seen zipping around at speeds up to 70mph, witnesses say in a police report. "Today is an incredibly sad day for the CarMax family," a company statement read. "Our hearts and prayers go out to our associate's family." One witness tells KTLA that when she heard the accident, which took place around 12:45pm just a couple of blocks away from the CarMax lot, she headed outside and saw Smale still in the passenger seat and Demetro on the ground clutching his shoulder. "I think he was probably shocked," she says. Smale was taken to a local hospital in critical condition and died there. "That guy had no idea today would be his last day when he showed up to work today," another witness told KTLA. Demetro is being detained in a San Bernardino County jail on $100,000 bail and is expected to appear in court on Thursday, per court records.
