Powell's husband, Josh, and their 2- and 4-year-old sons were at the service. Afterwards, Josh Powell didn't want to say a word or answer a question about his missing wife, but his brother-in-law did.
"We continue to hope she will be returned to us safely," said Kirk Graves.
With Josh standing next to him, Graves thanked the West Valley City Police Department, family, friends and complete strangers for helping them. He also said all the speculation about Josh somehow being involved in his wife's disappearance is upsetting.
"I think it's pointless. I think maybe worse than pointless. I think it's destructive and damaging to what's going on," said Graves. "There has been so much speculation that we just need to put it to rest."
Some of that speculation comes from Josh's story he told to investigators. He claims he took his young sons camping in the freezing cold of the West Desert on the night Susan disappeared from their West Valley home.
Graves said he understands how some could look at that story, but says his brother-in-law is just as hurt as anyone about his wife's disappearance. "I can tell you the pain he feels is real. I could feel it," said Graves.
As for the Powell children, the family said they're doing their best to keep them occupied and to shelter them from the situation. "Kids are very intuitive. You can see the stress," said Graves.
Investigators searched the Simpson Springs area of the West Desert Friday. Simpson Springs is a location off the Pony Express Trail where Josh Powell told police he went camping. Investigators didn't find anything, and a spokesperson with the West Valley Police Department said there are no updates.
When asked if Josh Powell had been to the scene to help police, Graves said he didn't know. Even with Powell standing next to him, Graves said there are some things his brother-in-law doesn't want to talk about.
"Josh is just here mostly to let everybody know that he's here and that he cares," said Graves. "What little detail facts I have, the police have asked us to not be open with them, to kind of keep quiet on what little we know that isn't well published. Our next step is to make sure everybody stays focused on Susan."
