07:51Oh, you're the one transporting?

07:53Yeah.

07:54Oh, okay.

07:55That clarifies being done.

07:56Cause we weren't really told.

07:58Yeah.

07:59He wants her to go right downtown.

08:01Okay.

08:02Cause we just had, he brought one back the other night.

08:07Well, he didn't, but ag robbery and they at least gave us a little bit more information

08:14saying that they were ready to take her.

08:15So I think he called them to verify that they were going to take her and they said yes

08:21with the charges.

08:22We didn't get that information cause I know Mace called us and told us a little bit,

08:27but not that cause there was some confusion cause of the age.

08:30Okay.

08:31Maybe it changed.

08:32I mean, she's 18 now, so.

08:34That's, that's the only holdup that we had is we weren't sure if she was going to County County

08:38or.

08:39Well, I think because at the time that I'll, I'll tell you more, but.

08:43Um, I don't know if you want to put her in a holding and.

08:46No.

08:47Yeah.

08:48Um, we'll hold up.

08:49All right.

08:51I don't know.

08:52You're an adult.

08:53So as soon as we're done doing what we're doing, you'll be able to make fun.

09:06Yeah.

09:07We have to wait for the detective to come back so we can figure out.

09:09Just have a seat for us.

09:11She was a bright-eyed teenager with dreams of fashion and love.

09:18He was her boyfriend since high school.

09:20Together, they were inseparable until they weren't.

09:24On a quiet morning in Strongsville, Ohio, Mackenzie Schirrilla drove her car into a building

09:32at over 100 miles per hour, killing him and another friend instantly.

09:38But was it just an accident?

09:41Or was it calculated?

09:43The court called her a killer.

09:45Her family calls her a victim of medical mystery.

09:48The black box told one story.

09:51Her silence told another.

09:53This is the fatal case of Mackenzie Schirrilla.

09:57And the devastating question at its core.

10:00Did she commit murder behind the wheel?

10:03Welcome to The Dark Stories.

10:06This is the channel where we journey deep into the shadows of crime, tragedy and the human psyche.

10:13Today's case asks us to examine what happens when love turns toxic, when youth meets trauma

10:21and when justice isn't so black and white.

10:24We bring you the tragic and chilling case of Mackenzie Schirrilla.

10:29The teen whose car became a weapon and whose life may never be the same.

10:34It was early morning, around 5.30am, on July 31st, 2022.

10:41A 2018 Toyota Camry came hurtling down Progress Drive, a dead-end industrial road in Strongsville, Ohio.

10:51There were no traffic lights, no people.

10:55Just one brick warehouse at the end.

10:58Inside the car were three people.

11:00Mackenzie Schirrilla, 17 years old, in the driver's seat.

11:05Her boyfriend, Dominic Russo, 20.

11:09And in the back seat, their friend Davian Flanagan, just 19.

11:14According to the vehicle's black box, the car was moving at more than 100 miles per hour

11:21when it ploughed directly into the warehouse wall.

11:25There was no attempt to brake, no swerve, no hesitation.

11:30Russo and Flanagan died instantly.

11:33Mackenzie was found unconscious, not breathing and badly injured.

11:38It took 45 minutes for anyone to discover the crash.

11:43And when first responders finally arrived, they couldn't make sense of what they saw.

11:49To those who knew her, Mackenzie Schirrilla was like any suburban teen.

11:55A high school senior with an interest in fashion design.

11:59She posted TikToks.

12:01She vaped.

12:02She smoked weed.

12:04She had big dreams and a steady boyfriend in Dominic Russo.

12:08A local favourite known for his easy charm and big heart.

12:13Their romance started when Mackenzie was just 14.

12:17Dominic was older, more confident.

12:21They were together for nearly four years.

12:24To their friends, they looked like soulmates.

12:27But behind the Instagram photos and birthday dinners,

12:31there were signs of something darker.

12:35By late 2021, the couple was living together in one of the Russo family's homes.

12:42But according to Dominic's mother, Christine Russo, the relationship was unravelling.

12:48She described fighting, breakups, shouting matches and even threats.

12:54In the final months, Christine said Mackenzie became possessive and Dominic often looked worn down by it.

13:02One chilling moment, just weeks before the crash, was overheard during an argument.

13:08Mackenzie allegedly shouted,

13:11I'm going to wreck this car right now.

13:13Another time, video footage showed her trying to break into Dominic's home.

13:19Were these empty threats from a heartbroken teen?

13:23Or warning signs of what was to come?

13:26The night before the crash started out normal,

13:2910.15pm, Mackenzie, Dominic and Davian attended a graduation party.

13:3611pm.

13:38They left the party and went to a friend's house to hang out.

13:42There, some of them smoked marijuana and they listened to music.

13:47Then, as dawn approached.

13:495.30am.

13:51The trio left.

13:54And minutes later, Mackenzie's Camry flew down Progress Drive and collided with the warehouse.

14:01There were no skid marks.

14:03No sign of evasive action.

14:06When investigators arrived, what they initially thought was an accident soon turned into a homicide investigation.

14:15The key to the case was the black box, the car's event data recorder.

14:21According to forensic analyst Mark Sargent, the data revealed that

14:26the accelerator pedal was fully pressed in the final five seconds.

14:31There was no use of the brake.

14:33The car experienced a hard right steering movement and was shifted between neutral and drive in a strange pattern.

14:42There were no mechanical failures.

14:45The engine was working perfectly.

14:47So was the brake system.

14:50Mackenzie's fuzzy slipper was found wedged between the gas pedal and floor mat.

14:55But Sargent concluded it could not have caused unintended acceleration.

15:01The conclusion, someone, intentionally, floored the gas until impact.

15:08Mackenzie was also found to be under the influence of marijuana and had psilocybin mushrooms, a psychedelic, in her possession.

15:18But perhaps more damning was the trail of digital evidence.

15:22Detective Zaki Hazu uncovered over 100 examples of dangerous driving on Mackenzie's social media.

15:31Driving while high.

15:33Driving while recording TikToks.

15:36Speeding.

15:37Swerving through traffic.

15:39All of it painted the image of someone who treated driving recklessly, not seriously.

15:45The prosecution believed this history, combined with the fractured relationship, created a clear motive.

15:54The trial was held in August 2023.

15:58Mackenzie faced 12 charges, including two counts of murder, aggravated vehicular homicide, felonious assault and drug possession.

16:09Because it was a bench trial.

16:10Because it was a bench trial, there was no jury.

16:13Her fate was in the hands of Judge Nancy Margaret Russo.

16:17No relation to Dominic.

16:19The judge didn't mince words.

16:22She called Mackenzie, hell on wheels, and said, this was not reckless driving.

16:29This was a mission.

16:30And she executed it with precision.

16:33The decision was death.

16:35She was sentenced to two concurrent 15 years to life terms, with the possibility of parole after 15 years.

16:43Her driver's license was revoked for life.

16:47Mackenzie gave a tearful apology in court.

16:50To the families of Dom and Davian.

16:53I am so deeply sorry.

16:55I wish I could remember what happened.

16:58I'd never do this on purpose.

17:00I'm heartbroken.

17:02But Mackenzie's parents, Steve and Natalie Sherilla, say the court got it wrong.

17:09They believed the crash may have been caused by a medical event.

17:14Specifically, a loss of consciousness, backed by health data they claim was ignored in court.

17:21They also point to text messages from Dominic, apologizing and suggesting he may have been the aggressor in some of their fights.

17:30Steve Sherilla said, show me one piece of evidence that says she did this on purpose.

17:36There isn't any.

17:38There's no proof what really happened inside that car.

17:41Her new legal team has already filed appeals and post-conviction relief motions.

17:47But so far, the conviction has been upheld.

17:51Still, the fight continues.

17:54The heartbreak extends far beyond the courtroom.

17:58Dominic Russo and Davion Flanagan, both young men full of potential, are gone.

18:05Forever.

18:06Dominic's sister said,

18:08I can't imagine how I'd feel if Mackenzie gets out in fourteen years.

18:13My brother doesn't come back in fifteen years.

18:16But Dominic's father, Frank Russo, surprised many with his compassion.

18:22I lost my son.

18:24It's unbearable.

18:25But she's a kid too.

18:27Her parents are destroyed.

18:29I wish there was a way she could get help.

18:32Some kind of treatment.

18:34I don't want her life completely ruined.

18:37It's a tragic irony.

18:39That even among grief, there's empathy.

18:43The case of Mackenzie Sherilla is full of contradictions.

18:47The law called it murder.

18:49Her parents call it a medical episode.

18:52The car's black box told a story of precision.

18:56Mackenzie says she remembers nothing.

18:58And somewhere between the facts and the feelings.

19:02Two families are shattered.

19:04And two boys are never coming home.

19:07Was this a crime of passion?

19:10A moment of madness?

19:12Or the final chapter of a toxic love story gone horribly wrong?

19:16No matter the verdict, this case leaves behind one haunting truth.

19:22Some tragedies have no easy answers.

19:25A moment of madness.
