The criminal investigation into the cause of the disaster with flight MH17 in eastern Ukraine is going well, according to chief prosecutor Fred Westerbeke. The chief prosecutor of the Public Prosecutor's national office said on Tuesday that though the investigators haven't reached the point of "formally" identifying suspects, they have a group of potential suspects in view, NU reports. "We are getting closer to legal and convincing evidence." he said. According to the Public Prosecutor, the most likely scenario is that the Malaysian Airlines airplane was shot down by a BUK-missile. But that is not the only scenario that the Prosecutor is looking at. Experts are busy investigating alternative scenarios in order to substantiate or exclude them. The families of the 298 victims were also informed of the status of the investigation on Tuesday.
