No, we know the guy wasn't 18...because this occurred in 2012 & Lds church didn't allow 18 yo missionaries that year.
The guy was 18 or 19; the girl was 16 or 17. Stupid law.
There's a fair number of church-based youth workers who are 19 & 20 years old.
So, you must be one of those upstanding "moral" types who advocates for sex 'tween 19 & 20 yo church youth workers & 16/17 yo girls within the youth group, eh???
I do not advocate church-based anything. Our Constitution does not, and I do not, recognize any religion or religious group as having any authority, moral or legal, over US citizens.
Any religion or religious group attempting to exert "authority" over any citizen of the USA is attempting to impose some "form of tyranny over the mind of man" that violates the rights of free citizens.
I do not care what religion you escaped from, or what religion you are now enslaved by, or what religion dominates your obsessions, whether for or against.
In this country, people have a right to worship as they see fit, so long as they do not infringe on the rights of others in the process. Unfortunately, most religions and religious people are not content to respect the rights of others.
In My Not-So-Humble Opinion, churches and religions are for those who cannot, or choose not to, believe in God. The church or religion serves as an idol for those people to worship until they are ready to believe, if ever. People can flee from one church to another, from one set of lies to another, and they will still find that any group of people will be corrupted just like any other group of people.
If the zealots could or would read for themselves, they could find one of those Bibles with red letters in the New Testament for the parts that Christ said, and black letters for everything that the idiot disciples made up to fill in the blanks.
Christ had pretty much the same opinion of organized religion as I have expressed above. The idiot disciples went out and created exactly what he told them to avoid, and subsequent centuries of idiots have propagated the idiocy. Relatively few have ever paused to ask God to help them see the truth; relatively few have recognized or accepted any piece of truth that God has revealed in the past two millenia; relatively few have any interest in seeking truth or honesty. Watch. More idiots will spring forth below to prove my point, babbling the same nonsense someone else told them to babble, and which they have never had the faith, courage, or integrity to personally question or investigate.
