(PITTSBURGH) — As the investigation to identify suspects entered its fourth day in a mass shooting at a Pittsburgh Airbnb house that left two teenagers dead, police amended the number of gunshot survivors from eight to nine.

The Pittsburgh Police Department said in a statement that the new non-fatal gunshot victim was taken to a hospital in a private car and arrived at an emergency room on the morning of the shooting in stable condition.

Pittsburgh Police Chief Scott Schubert said another five people suffered cuts and broken bones fleeing the gunfire, some by jumping from second-story windows.

No arrests have been announced in the shooting that occurred early Sunday morning during a party at an Airbnb rental in the East Allegheny neighborhood of North Pittsburgh that police said was attended by more than 200 people.

Schubert said Tuesday that about two hours before the shooting erupted, a police officer responded to a noise complaint at the Airbnb house, but left after issuing a verbal warning to keep the noise down.

“There was nothing unusual to indicate that something was wrong,” Schubert said. “We have some information that shows that a lot of these people didn’t come until after midnight.”

The shooting erupted around 12:40 a.m. Sunday, and investigators collected 90 shell casings from the scene, including 50 from inside the Airbnb home.

Schubert said the shooting broke out after an “altercation” inside the house, but has declined to elaborate.

The Allegheny County Medical Examiner’s Office identified the two 17-year-olds killed in the shooting as Mathew Steffy-Ross and Jaiden Brown. Both teens were scheduled to graduate from high school in June, according to friends and loved ones.

“Matthew was a fun, loving kid that cared so much about everybody. Matthew would give you the shirt off your back,” Steffy-Ross’ great-aunt, Bonnie McLain, told ABC affiliate station WTAE-TV in Pittsburgh.

She described Steffy-Ross, a senior at Grace Non-Traditional Christian Academy in Pittsburgh, as having “the biggest smile in the world.”

“He cared about people and he loved people, and he acted upon it,” McLain said, adding that she last spoke to her nephew on Saturday morning and heard of his death from a neighbor on Sunday.

Pittsburgh community activist Lee Davis of the Greater Valley Coalition Against Violence told WTAE that he was a mentor to both Steffy-Ross and Brown.

“I have been to over 100 funerals in the 17 years I have been doing this work, and I thought I was all cried out, but when I seen what happened to Jaiden and Matt, the tears just came all over again,” Davis said. “It just hurt my heart.”

Davis said he knew Brown, a senior at Woodland Hills High School in Pittsburgh, since he was a child.

“His energy was great,” Davis said of Brown. “Everybody loved him, and he became very well-liked in the community. To see this happen to him was really heartbreaking … because he had a very bright future.”

Cathy Jo Welsh, a member of the youth anti-violence program Helping Out Our People in Pittsburgh, said Brown’s father died from an illness a few years ago and that Steffy-Brown’s mother died recently.

“(Steffy-Brown) was just getting his bearings from losing his own mother and just learning how to live with trauma and grief,” Welsh told WTAE.

(NEW YORK) — The man accused of pushing a New York City woman to her death in front of an oncoming subway train in January was deemed unfit to stand trial at a court hearing Tuesday in accordance with findings from a psychiatric evaluation.

Simon Martial, 61, will now be sent to a psychiatric facility under the custody of the city’s Department of Mental Health and Hygiene, according to Manhattan District Attorney Alvin Briggs’ office.

The DA’s office did not contest the determination, but told ABC News that the office will continue to review the case and pursue Martial’s conviction.

Michelle Alyssa Go had been standing on the southbound N/Q/W/R platform at Times Square station on Jan. 15, looking at her phone, when she was suddenly shoved, unprovoked, onto the tracks, police say. She was pronounced dead at the scene just weeks after celebrating her 40th birthday.

Martial, who is homeless, fled the station but turned himself in later that day, according to police. He was charged with second degree murder.

New York County Defender Services, which is representing Martial, declined to comment Wednesday when reached by ABC News.

Though police have not classified the tragic attack as a hate crime, Go’s death heightened anxiety around a rise in anti-Asian sentiments and violence, weighing heavily on many as they came together for vigils in Times Square and San Francisco’s Chinatown in honor and remembrance of the Fremont, California, native and several other Asian crime victims back in January.

Go was a consultant for Deloitte and a longtime volunteer and advocate for the homeless, according to ABC affiliate WABC-TV.

Her family released a statement describing her as a “beautiful, brilliant, kind, and intelligent woman who loved her family and friends, loved to travel the world and help others.”

(BETHANY, Conn.) — A Connecticut State Police trooper was arrested on a felony manslaughter charge after a report by the state inspector general alleged his use of deadly force was not justified in the January 2020 shooting of a 19-year-old Black man.

Trooper Brian North, 31, surrendered Tuesday at the state police barracks in Bethany, Connecticut, after a warrant was issued for his arrest in connection with the fatal shooting of Mubarak Soulemane, state police said.

State Inspector General Robert Devlin Jr.’s investigation found that although Soulemane was allegedly armed with a steak knife, had stolen a Lyft rideshare vehicle and was apparently off his medication for schizophrenia, he was not a threat to North and other officers when he was shot multiple times, according to the report released Wednesday.

Soulemane was killed when North allegedly fired seven times at him through the closed driver’s side window of a stolen Lyft vehicle after troopers stopped him and pinned him in on Interstate 95 in West Haven following a chase that reached speeds of 100 mph, according to the report.

Delvin’s investigation found that Soulemane was sitting behind the wheel of the car surrounded by troopers and officers from other agencies and was trapped inside because North’s cruiser was blocking the driver’s side door.

An officer from the West Haven Police Department was bashing in the passenger-side window with a baton and another trooper was poised to deploy a stun gun on Soulemane when North opened fire as Soulemane reached into his pocket and pulled a knife, according to the report.

“Stated briefly, the investigation establishes that, at the time Trooper North fired his weapon, neither he nor any other person was in imminent danger of serious injury or death from a knife attack at the hands of Soulemane,” Devlin concluded in his report. “Further, any belief that persons were in such danger was not reasonable. I therefore find that North’s use of deadly force was not justified under Connecticut law.”

North, a seven-year veteran of the Connecticut State Police, was booked on a charge of first-degree manslaughter with a firearm, Devlin said in a statement. North was released on $50,000 bond and is scheduled to appear in Superior Court in Milford on May 3.

‘A good day’

North was placed on administrative leave and his police powers have been suspended pending criminal proceedings, according to state police.

Mark Arons, the attorney for Soulemane’s family, said the arrest marked “a good day” for the family.

“This is the first step in the journey for justice for the wrongful killing of a 19-year-old Black youth in Connecticut…The family looks forward on this matter being tried and this state trooper being convicted,” Arons said in a statement.

The incident unfolded on Jan. 15, 2020, in Norwalk, Connecticut, after police received a complaint that Soulemane was armed with a knife and acting erratically at an AT&T store, according to Devlin’s report.

Police were called to the store, but Soulemane left in a Lyft vehicle as they arrived. The Lyft driver told police that Soulemane ordered him to “drive, drive, drive” when he got into the car, according to the report.

The driver alleged that Soulemane demanded his cellphone and slapped him on the side of the head when he refused, the report says. The driver told police he drove to a gas station and got out of the car, pulling a gun on Soulemane and flagging down a police officer, according to the report.

Soulemane allegedly jumped into the driver seat and fled, prompting the police chase.

Trooper claims he was protecting officers

North told investigators, according to the report, that he opened fire because he was concerned that the officers on the passenger-side of the car were in “imminent risk of serious physical injury or death.”

“As a result, I discharged my duty firearm to eliminate the threat,” North told investigators, according to the report.

North’s attorney could not immediately be reached for comment Wednesday.

Connecticut State Police Union officials released a statement to ABC affiliate station WTNH-TV in New Haven, saying they are “disappointed” in the inspector general’s decision to prosecute North.

The union added that North “was forced to make a split-second decision during these dangerous and rapidly evolving circumstances.”

The union asked the public to reserve judgment “until all facts are known in this case.”

“Trooper North was risking his own life while trying to fulfill his oath of office to protect the lives of others,” the union’s statement said. “Regardless of the Inspector General’s decision, we will respect the judicial process while we vigorously defend Trooper North and his actions. It is our obligation to protect Trooper North’s constitutional right to due process of law and a fair trial.”
