Was Silas with Paul in Rome?

Silas was not with Paul in Rome during his imprisonment; instead, he was last mentioned in the Book of Acts as accompanying Paul on his second missionary journey. By the time of Paul's letters written from Rome, such as those to the Philippians or the Colossians, Silas is not mentioned, indicating he was likely elsewhere. Paul often worked with various companions, and it is believed that he may have been alone or with different associates during his time in Rome.
