You should use "Russ's" in this case, as it is the correct possessive form for a singular noun ending in "s." Therefore, the correct sentence would be "Russ's laptop was stolen last week." This usage is consistent with standard English grammar conventions.
To write "Russ's," you simply add an apostrophe followed by the letter "s" to the name Russ. This indicates possession, meaning something belongs to Russ. For example, you might say "Russ's book" to refer to a book owned by Russ. If you're referring to multiple people named Russ, you would write "Russes'" with an apostrophe after the "s."
