Sam was born in Cleburne, Texas to a
Texas Ranger and a stay at home mother. He grew up with an healthy interest in
the criminal justice system. At 18 he applied to join the Rangers. However, he
was not accepted. So, he did the next logical thing and joined Starfleet. While
he took the aptitude test, he wasn't surprised when it said he'd be perfect for
the Armory Department.
Upon completion of his training, he was
assigned to the same Neptune Class vessel that Megan Galloway was aboard. The
pair got along well although they were nothing more than friends. When Megan was
transferred to the Challenger, Sam applied for a transfer as well. His transfer
was granted and he joined the Challenger about a month after Megan. He was among
the four picked to form the Avengers.
