After the first strike, the two survivors were in electronic communication with another ship suspected of being involved in narcotics trafficking, two people with knowledge of the matter said.

The details of that communication are unclear, but commanders at the Pentagon could cite the survivors' contact with a “mothership” as evidence that they were continuing to pursue drug smuggling efforts and therefore were legal targets, the sources said.

不知道通话内容，也许通话是在喊救命呢。
