The jury deliberated for a full day Thursday without reaching a verdict in the trial of Connecticut State Police trooper Brian North, who faces a manslaughter charge in the fatal shooting of 19-year-old Mubarak Soulemane.

The full day of deliberations came a day after the six jurors heard closing arguments from both North’s attorney, Frank Riccio, and Inspector General Robert Devlin Jr. Devlin charged the 33-year-old trooper with first-degree manslaughter with a firearm after his investigation into the shooting concluded his use of deadly force was not justified.

North fired seven shots at Soulemane after a high-speed pursuit on Interstate 95 ended off of Exit 43 on Campbell Avenue in West Haven just after 5 p.m. on Jan. 15, 2020. Troopers partially boxed in the Hyundai Sonata Soulemane had stolen after he crashed into another motorist in a Chevrolet Trailblazer.

Soulemane, who was initially unconscious as police approached, came to when West Haven Officer Anthony Rappa used a baton to smash out the passenger side window, according to testimony. He began reaching toward his waist before grabbing a serrated kitchen knife and raising his arm.

North took the stand last Friday when he told jurors he fired believing Rappa had started entering the vehicle to extricate the teen and that the West Haven officer or Trooper Joshua Jackson, who was near the broken window, could have been seriously injured or killed.

Devlin has contended that North never believed Rappa or Jackson were ever in any danger, as he did not mention protecting them when asked by a supervisor at the scene what happened. He only mentioned that the men could have been in danger after reviewing body camera and cruiser footage of the incident and writing a statement on the shooting with an attorney and a union rep present, Devlin has said.

Riccio has insisted North was only following his training when he fired his weapon and that he did so during a split-second decision genuinely believing he needed to to protect Rappa and Jackson. In his closing arguments, Riccio accused Devlin of prosecuting the trooper for simply doing his job and told jurors his client’s actions were “objectively reasonable” — a term he said should serve as the crux of the case — and that another reasonable officer would have done the same thing.

The six jurors deliberated for about an hour on Wednesday afternoon and for about another six hours on Thursday in the Ansonia-Milford Judicial District Courthouse. Following closing arguments, Judge H. Gordon Hall instructed the jury on what elements they should consider when reaching a verdict and explained the differences between first-degree manslaughter with a firearm and two lesser charges — including second-degree manslaughter with a firearm and criminally negligent homicide — they could consider.

After informing court officials Thursday afternoon that they had not yet reached a verdict, the jury was excused for the day just after 4:30 p.m.

Deliberations are expected to resume at 9 a.m. on Friday.

Jurors were interrupted briefly when they lost the audio on the laptop they were provided that allows them to examine any of the evidence presented, including body-worn cameras and cruiser footage from police at the scene.

Hall received a note from jurors just before 3 p.m. about the audio issue before the laptop was brought into the courtroom. Deputy Inspector General Andrew Slitt was able to get the audio working and had the computer returned to the jury in less than 10 minutes.

As supporters of North and protestors eagerly awaited a verdict, North spent much of the day in the defendant’s chair alongside his wife without a judge on the bench. Soulemane’s family members — who have attended the entirety of the trial — came into the courtroom periodically when Hall took the bench, including when he announced deliberations would continue into Friday.

Outside the courthouse, supporters of North placed Blue Lives Matter flags on the lawn and signs with messages like “Real heroes die serving the law, not resisting it” and “Stand with North.” Protestors put signs up that read things like “Protect and serve does not mean murder teenagers” and “Police are not judge, jury and executioner.”

In the first of eight days of testimony, jurors heard from Soulemane’s mother and sister, who said he had his first psychotic episode at 15 years old and had been prescribed medications, which he struggled to regularly take, for schizophrenia and bipolar disorder. Soulemane’s sister and girlfriend both testified that the teen appeared to be undergoing an episode in the days leading up to the shooting.

Soulemane had gone to an AT&T store in Norwalk at 4:15 p.m. where he acted erratically and tried buying a phone, but he did not have good enough credit or enough money, an employee testified. He requested a ride from the Lyft app after entering and exiting the store multiple times.

The Lyft driver, Daniel Green, testified that Soulemane asked him where they were going and asked for his phone. When Green refused, Soulemane slapped his head and he agreed to give him the phone before pulling over in a Shell gas station. Once he stopped, Green got out of the Sonata and drew his legally owned firearm.

According to Green’s testimony, Soulemane exited the vehicle and got into the driver’s seat before driving away and smiling at a Norwalk police officer who had just arrived. Police pursued the vehicle onto Route 7 before canceling the pursuit.

State police began pursuing the Sonata on I-95 upon being incorrectly told it was stolen during a carjacking. Soulemane during the chase drove between 80 and 100 mph and struck multiple vehicles, including troopers who tried to box him in.

The pursuit ended when Soulemane got off the highway and crashed the Sonata.
