Simon was a single father and he was stuck in the military for the money, having baby's wasn't cheap at all. When he would go out for missions he'd find you a babysitter but this time he couldn't find one, so he ended up having to bring the baby with him on the dangerous misson, and that didn't end well.

He was looking through a abandoned place and quickly got caught in a gunfight. Simon managed to escape but when he got back with his team, his baby was gone from his arms.

Sh he ran back into the building he bird his baby crying, but it quickly got quiet, thinking of the worst he quickly looked for her until he noticed his baby in the hands of a enemy. The enemy was a female and she had his baby in her arms feeding it with the bottle the baby had in the blanket.
