Phone records, documents, interviews and thousands of hours of video expose the main Russian military unit responsible for a devastating atrocity: the killing of dozens of people along one street in Bucha, Ukraine. nyti.ms/3WsAm7M

We didn’t just find evidence of this unit’s presence on Yablunska Street. We caught them in the act. Vehicle markings seen in CCTV, calls made by soldiers from victims’ phones hours after their killings, and more evidence all place the unit at the scene at the time of the crimes.

As part of this effort, we compiled a visual record of killings along Yablunska Street. This was based on dozens of photos and videos from the street captured after the Russian retreat at the end of March. We used those visuals to map out where each person was killed.

We analyzed hours of drone and CCTV footage, along with satellite imagery, to establish a timeline of when exactly the killings of 40 people along Yablunska Street took place. Then we set out to identify them — and the Russian unit implicated in each of their killings.

Pavlo Valko was shot days after celebrating his 33rd wedding anniversary, on his way to visit his mom. Zhanna Kameneva was killed along with three others she was helping escape, including a 14-year-old girl. Read more about their final acts of kindness: nyti.ms/3FPU6eT

Linking the killings to a specific unit is the only way families may one day see perpetrators in court. All along Yablunska Street, including in the killings of Pavlo and Zhanna, the evidence points toward one unit: the 234th Guards Air Assault Regiment. nyti.ms/3jjpBGy

@ckoettl And from @YousurAlhlou about another damning trove of evidence she and @MashaFroliak dug into: phone calls soldiers made using the cell phones of the victims.

@ckoettl @YousurAlhlou @MashaFroliak To recognize a few of the people involved in this effort: @YousurAlhlou and @MashaFroliak — our dogged reporters in (and out of) the field, who made much of this possible. Words can’t express how much admiration I have for them…

@ckoettl @YousurAlhlou @MashaFroliak …which extends to @ckoettl and @dim109 (who I've been in the weeds with on this reporting since April) and the stellar team of @ajcardia @NatalieReneau @malachybrowne and @markscheffler. Important contributions from @evanhill @ishaan_jhavs @julianbarnes @msalexkoroleva and more.

@ckoettl @YousurAlhlou @MashaFroliak @dim109 @ajcardia @NatalieReneau @malachybrowne @markscheffler @evanhill @ishaan_jhavs @julianbarnes @msalexkoroleva Finally, this piece about 36 Ukrainians killed on Yablunska — a small glimpse into the more than 400 killed in Bucha during the occupation — wouldn't have been possible without @alizauf @the_log_lady and @hanaansarhan. We hope you take the time to read it. nyti.ms/3FPU6eT
