It would appear that Troy D Larsen was living at 76 Garden St, Malden, MA 02148, but this may be an old # and would necessitate a snail mail letter as there is no phone or e-mail listed.
411 confirms this is the right person as they have him with Lynn A Derby:

I am assuming his birthdate is 6/20/1978...

And how odd that there is a Chad E Larsen with the exact same date of birth living in Salt Lake City, Utah. Does he have a twin borther? Troy is #5 and listed as living in Boston, MA, but showing no relatives.
Intellus seems to have the most info on where he has been, starting in Salt Lake City, then Layton, UT, then Malden, MA, then Boston, MA.
I'm wondering if Lynn A Derby is 31 as I found one who is 31 in Malden, MA on Intellus. I also found one 31 who lived in West Springfield, moved to Allston, MA and then to Boston, MA. Unsure if they are the same one, but if they are,

This could be her listed with her Derby family at 413-732-5903. At least it gives you a phone number and if they are not still together, she may be able to give you a new address and/or phone.
He is not registered to vote in the city of Boston with that name and date of birth.
I don't know what he looks like, but have you tried Facebook and MySpace?
