Cause of death released for Redwood City inmate Kyle Harrison
(KRON) — A Redwood City street racer died in jail earlier this year shortly after he was sentenced for his role in causing a crash that left twin girls orphaned. On Monday, the San Mateo County Sheriff's Office released Kyle V. Harrison's cause of death.
The county coroner's office determined that Harrison died on March 15 at Maple Street Correctional Facility in Redwood City 'due to toxic effects of three medications,' the sheriff's office wrote.
The coroner concluded that the 25-year-old inmate's manner of death was an 'accident' and found Harrison died due to toxic effects of Methadone, Amitriptyline, and Gabapentin.
Harrison previously pleaded no contest to engaging in a speed contest and felony vehicular manslaughter for the deaths of Grace Spiridon, and her husband, Gregory Ammen. The couple's 7-year-old daughters 'miraculously' survived the crash on El Camino Real, prosecutors said.
In February, Harrison was sentenced to serve eight years in state prison. Court records show that Harrison was slated to be transported from the county jail to a state prison facility in May, but he died in jail before he was transferred.
Investigators did not say why Harrison was taking Methadone, a medication typically used to treat opioid use disorder. Amitriptyline is an antidepressant medication. Gabapentin is an anticonvulsive medication that's also used to treat certain types of neural pain.
The street race happened on Nov. 4, 2022 in Redwood City. Harrison raced his BMW against a teenager, Cesar Salto Morales, who was driving a Mercedes Benz on El Camino Real. Morales' Mercedes slammed into a Chevrolet Bolt with Spiridon, Ammen, and their two young daughters inside.
The parents were killed on impact, while their daughters survived in the backseat. The family was less than 10 minutes away from their San Carlos home. Prosecutors said Harrison fled the scene, and a witness recorded his BMW's license plate number with her cellphone as he was driving away. Police found and arrested Harrison weeks later.
After his in-custody death, the San Mateo County District Attorney's Office and San Mateo County Coroner's Office conducted independent investigations into Harrison's cause and manner of death. The DA's investigation is still underway.

Teen boy killed in fiery multi-vehicle crash in Pompano Beach, 5 others hospitalized, BSO says
A teenage boy is dead and five people were hospitalized after a fiery crash involving multiple vehicles in Pompano Beach on Friday night, authorities said. Just before 8 p.m., the Broward County Sheriff's Office responded to a multi-vehicle crash and car fire near 200 West Copans Rd. According to investigators, the preliminary investigation revealed that a 2019 Mercedes-Benz CLA 250, which a 16-year-old boy drove with a 17-year-old female passenger and three 17-year-old male passengers, was traveling west on West Copans Road and approaching Leisure Boulevard. Meanwhile, a 2021 Toyota Sienna, driven by an 82-year-old man, was traveling south on Leisure and approaching West Copans. BSO detectives said that at some point, the Sienna turned left when it collided with the Mercedes. The collision caused the teenage boy to lose control of his car, which rolled onto its roof as it slid southwest across the road and into eastbound traffic, colliding with a 2015 Lexus RX 350. Also, BSO said a 2021 Toyota RAV4 was traveling east on West Copans and was struck by debris as the Mercedes slid by. BSO deputies at the scene began life-saving measures until Pompano Beach Fire Rescue arrived and took all the Mercedes' occupants and the Lexus' driver to the hospital for treatment. However, the 16-year-old boy died at the scene, BSO said. BSO said the Sienna and RAV4 drivers were not injured and remained at the scene and cooperated with investigators. According to BSO, detectives said excessive speed may have been a contributing factor, but the circumstances surrounding the crash remain under investigation.

Wrong turn sends driver down Spanish Steps, car lifted by crane, video shows
An elderly man's wrong turn down a famous Italian landmark led to his vehicle being craned away. An 80-year-old man on his way to work mistakenly drove his Mercedes-Benz sedan down Rome's famous Spanish Steps in the early morning June 17, Italian media reports show. Video captured the driver slowly navigating down the historic stairs before getting stuck as well as the audio reaction of bystanders in disbelief. Police said the man exited the vehicle uninjured and firefighters used a crane to remove the vehicle from the steps, Italian outlet Il Corriere della Sera reported. Public access to the Spanish Steps was temporarily restricted while experts with the Ministry of Culture examined the extent of damage caused by the driver, according to CBS News. Upon being taken to a local hospital, the man tested negative for both alcohol and drug consumption, CNN reported citing city police. However officers said the driver appeared to be in a state of confusion, according to Il Corriere della Sera. He reportedly had a valid driver's license. The peculiar moment wasn't the first time a vehicle drove through the historic landmark. In 2022, a Saudi man was charged with aggravated damage to cultural heritage after footage captured a Maserati driving down the same steps. Build between 1723 and 1726, the Spanish Steps lead from the iconic Piazza di Spagna square to the French monastery church Trinita dei Monti, according to Rome's tourist site. The landmark features 135 total steps as well as three different terraces that reference the Holy Trinity or the Trinità. Tourists often visit the top of the stairs for a scenic view of Rome.
