(CNN) -- In the middle of the Idaho wilderness, a man on horseback had a brief conversation with two campers. The rider's realization later that he may have been talking to California Amber Alert suspect James DiMaggio and his alleged teenage captive has now focused a nationwide manhunt for the pair on the rugged mountain area in central Idaho.

The horseback rider saw the man and girl Wednesday and struck up a brief conversation with them, Andrea Dearden, spokeswoman for the Ada County Sheriff's Office, said Friday.

He was not aware of the manhunt at the time, but he called the Amber Alert tip line after he saw a news account that night and realized the pair matched the description of DiMaggio and 16-year-old Hannah Anderson, she said.

The rider's impression of the pair was "it seemed odd but nothing as alarming," Dearden said.

"They did speak and exchange pleasantries. I don't think there was a lot of information exchanged," she said. "He left the conversation believing they were camping in the area."

The rider said the man and girl were on foot, hiking with camping gear, Dearden said.

Dearden appeared to be correcting authorities' earlier reports that the suspect and girl were spotted by more than one horseback rider.

Investigators set up checkpoints where DiMaggio and Hannah were believed to be traveling in the River of No Return Wilderness area, about 15 miles outside Cascade, Dearden said.

Authorities haven't yet evacuated any homes or businesses, she said, adding, "We have those access points secured." What are the answers to this following set of questions: 1. What is the name of the teenage captive?

Years after throwing a bottle-up note into a lake for a class project and just one year after his death, a man's childhood message was found and returned to his mother.

Eleven years ago, a then 10-year-old boy, Joshua Baker, wrote the message, folded and put it in an empty container, his mother, Maggie Holbrook said. He died last February in a motor vehicle accident in California. He had recently returned after a serving in the Middle East as a US marine. "I think he was just letting us know he was OK and keep doing what we are doing." Holbrook said.

The message surfaced in White Lake in late April, just days after the 11th anniversary of its being thrown into the lake. It was found by one of Baker's closest friends, Steve Lieder, she said. Lieder and two friends were chatting near the lake when Lieder looked down and saw the bottle. He broke it open and found the note inside.

"My name is Joshua Baker. I am 10. If you find this, put it on the news. The date is 4/16/98." They immediately took it to Holbrook, who said she is now having the note preserved and will display it in her home.

She can remember when her son wrote the message for the school project. She said she always wondered why he didn't put it in the nearby Wolf River, which has a much stronger current.

"I still remember the day he wrote it, " Holbrook said. "I couldn't understand why he threw I in the lake. No one would never see it again. Now I know." What are the answers to this following set of questions: 1. How old was Joshua?
2. What was his last name?

(CNN) -- Overprotective sister? Underprotective husband?

No one knows what was said amongst Solange Knowles, Jay Z and Beyonce in that elevator in the Standard Hotel in Manhattan or even what led up to the video that appears to show Solange kicking and hitting her brother-in-law.

But here is what we do know: the Internet is on fire with theories.

Earlier this week, an elevator surveillance video surfaced that showed Solange appearing to berate Jay Z before she becomes physical. Her sister, Beyonce, is present and witnesses the attack.

The incident has inspired a hashtag, #WhatJaySaidToSolange, countless memes and tons of speculation.

Quoting an anonymous source, Us Weekly reported that Solange Knowles had an earlier run-in with designer Rachel Roy. (Roy is the ex-wife of Damon Dash, Jay Z's former friend and business partner.)

The New York Daily News, also using an unnamed source, took it one step further. In addition to the alleged argument with Roy, the paper threw in Jay Z's supposed desire to head solo to a party being given by Rihanna. This, according to the Daily News, did not sit well with Beyonce's younger sister.

Talk show host Wendy Williams also offered her own observations, including what appears to be the removal of a tattoo on Beyonce's finger of the roman numeral "IV." It was reportedly her wedding ring tattoo, meant to symbolize both her wedding date (April 4) as well as her and Jay Z's birthdays (September 4 and December 4, respectively).

So far, some of the principal characters seem to be letting Instagram speak for them. Beyonce has posted happy pictures of her and her sister, while Solange participated in "Throwback Thursday" with a picture of the two siblings as kids. What are the answers to this following set of questions: 1. Does anyone know what Jay said to Solange?
2. Who has theories about what was said?
3. Was Beyonce present when Solange hit jay?
4. What was one theory?
5. What else?
6. Did any of the parties involved say anything?
7. Did Beyonce remove a tatoo?
8. Why?
9. What did this represent?
