The people pursuing them at first targeted Ms. Liu’s sister in Short Hills, N.J., because they did not know Mr. Xu’s address.
Mr. McMahon enlisted other investigators to help him with the job, while exchanging messages with people from the “company” that hired him.
In 2017, Chinese officials forced Mr. Xu’s 82-year-old father to fly in from China in a bid to learn where Mr. Xu lived and to persuade him to return to the country, prosecutors said.
The officials enlisted Mr. McMahon to do surveillance during that trip in an effort to learn where Mr. Xu was living.
The following year, Mr. Zheng was one of two people who left a threatening note on the front door of Mr. Xu’s home.
