Malik has an affidavit from Kevin Miller swearing that you conspired with Sean Chill to get him and Mike out of prison.

【翻译】马利克有一份凯文·米勒提供的口供，他（指凯文）发誓说你和肖恩·奇尔密谋要把他和迈克从监狱里救出来。

swearing that you conspired with Sean Chill to get him and Mike out of prison，这是现在分词短语，作Kevin Miller 的定语。

现在分词作定语，表示“主动”，但不一定指“进行”。尤其是一些静态动词的现在分词，可以表示习惯性，可以转换为一般体，而非进行体。例如本句：

Malik has an affidavit from Kevin Miller who swears that you conspired with Sean Chill to get him and Mike out of prison.

又如：

Do you know the West Lake lying in the west of Hangzhou?

Do you know the West Lake that lies in the west of Hangzhou?
