Victim identified, suspect sought in fatal North Tonawanda shooting

North Tonawanda police detectives were looking for a 39-year-old Buffalo man Monday for questioning in the fatal shooting of one man and the wounding of another at about 1:30 a.m. Sunday at Manhattan and Tremont streets in North Tonawanda.

Meanwhile, police identified the dead man as Mark Sternin, 25, of the City of Tonawanda.

The other victim, Tyler Sadauskaus, 24, of North Tonawanda, remained in critical condition in Erie County Medical Center with a single gunshot wound, according to North Tonawanda Police Detective Capt. Thomas E. Krantz.

Investigators said they were searching for Dominic Cruz, who fled when detectives approached him Monday morning at his workplace, Speed Global Services on Kenmore Avenue in the Town of Tonawanda. Cruz is suspected of being one of three men seen speeding away from the scene of Sunday’s shooting.

The search for Cruz led to the temporary lockout Monday of the elementary and high school buildings of the Charter School for Applied Technologies on Kenmore Avenue when Cruz was suspected of having fled into one of them.

A 3½-hour lockout of both buildings at the Charter School for Applied Technologies in the Town of Tonawanda was lifted early Monday afternoon, after a sweep of a large commercial building nearby determined that the man being sought was not there, Town of Tonawanda police said.

The school lockout lasted from roughly 9:50 a.m. to 1:20 p.m., as police searched for Cruz who they believed might have been inside the Speed Global Services building near the school.

Both the school and business are on the Town of Tonawanda side of Kenmore Avenue, near Vulcan Street.

Detectives said Cruz, who is 5-feet-3 and about 140 pounds with short black hair and brown eyes, may be driving a white 2011 Chevrolet Impala with a black roof and black gas cap.

Anybody with information about the case is asked to call the North Tonawanda Police Detective Bureau at 692-4312 or North Tonawanda police dispatch at 692-4111.

Krantz stressed that individuals should not approach Cruz.

The shooting took place in a Manhattan Street parking lot.

Police put out a search request for three black males suspected in the shooting who left the area in a cream-colored car.

North Tonawanda police called their Town of Tonawanda counterparts at 9:47 a.m. to notify them that they were looking for the individual inside or near the Kenmore Avenue business.

Town police then called the school to initiate the lockout; that differs from a lockdown, when the perceived threat is inside, rather than outside, the building.

“The SWAT teams did their search of the (commercial) building, as well as the fields and the area surrounding the school,” Town of Tonawanda Police Capt. Joseph F. Carosi said. “He wasn’t there, and they lifted the (lockout).”

Authorities would not say whether they believed that the suspect was an employee of the Kenmore Avenue business or whether they had information that he might have been hiding there.

Gayle L. Syposs, chairwoman of the City of Tonawanda Democratic Party, said Sternin’s family was “devastated.” She called the Sternins “a wonderful family.” Syposs said she met Sternin briefly this past year when he helped on the campaign of his aunt, Heather L. Sternin, for the City of Tonawanda School Board.
