Convicted Cop Killer Served 25 to Life In Separate Case

Tried To Kill Rob Victim In Queens

A convicted cop killer was sentenced to 25 years to life in prison, last Wednesday, Jan. 15, as a mandatory persistent violent felony offender for the attempted murder and robbery of a Queens man in July 2007.

Queens District Attorney Richard A. Brown identified the defendant as Dexter Bostic, 40, formerly of Far Rockaway. Bostic, who is presently serving a term of life without parole for the murder of P.O. Russel Timoshenko in Brooklyn, was sentenced to 25 years to life in prison by Queens Supreme Court Justice Gregory L. Lasak, who ordered the sentence to run consecutive to Bostic’s life sentence.

The defendant was convicted in July 2013 of one count of seconddegree attempted murder, two counts of first-degree assault, two counts of first-degree robbery, two counts of second-degree criminal possession of a weapon and one count of fifthdegree criminal possession of stolen property following a four-week jury trial .

The shooting occurred less than 20 hours before Bostic fatally shot P.O. Timoshenko.

Brown said, “Today’s sentence ensures that the defendant-a dangerous predator who has been convicted of shooting an unarmed man and an on-duty police officer within 24 hours-will spend the rest of his life in prison and never again see the light of day.”

According to the trial testimony, the 20-year-old victim, was standing on the corner of Sutphin Boulevard and 109th Drive talking to a friend just before 5 a.m. on July 8, 2007, when a gray Porsche Cayenne being driven by Robert Ellis, 40, also of Far Rockaway, stopped at the corner. Bostic exited the vehicle holding a silver .45-caliber handgun and began shooting.

The victim attempted to run but was shot once in his left leg, the bullet shattering his femur, causing him to fall to the ground. Bostic then approached and demanded money. The victim handed over $1,800 in cash, a chain and the keys to his vehicle. Bostic and Ellis then fled in the Porsche.

Ellis was convicted of the same criminal charges as Bostic following a jury trial also before Justice Lasak and was sentenced in July 2013 to a determinate term of 25 years in prison. The sentence was ordered to be served consecutive to the 15-year prison sentence Ellis was serving for a weapons possession conviction stemming from the July 9, 2007, fatal shooting of Officer Timoshenko.

In that case, the stolen black BMW SUV in which Ellis, Bostic and another individual were riding was pulled over by police officers Russel Timoshenko, 23, and Herman Yan, 27, when it was noticed that the license plate on the car had been reported stolen from a Mitsubishi Outlander.

As the two officers approached the vehicle, they were shot at multiple times-including by the gun used the day before to shoot the Queens robbery victim.

Officer Timoshenko died five days later from the wounds he suffered in the attack. Officer Yan, who was also severely hit, survived.

The investigation was conducted by Det. George Whalley of the 103rd Precinct in Queens, as well as Det. Peter Margraf and Lt. Andrew Ferris of the 71st Precinct in Brooklyn.

Assistant District Attorneys Robert J. Hanophy, deputy bureau chief of the District Attorney’s Career Criminal Major Crime Bureau, and Patricia M. Theodorou, bureau supervisor, prosecuted the case under the supervision of Assistant District Attorneys James W. Evangelou, bureau chief, and the overall supervision of Senior Executive Assistant District Attorney for Trials James C.
