The search for 7-year-old Joshua "JJ" Vallow and his sister, Tylee Ryan, 17, has entered its fifth month. The disappearance of the two siblings from Rexburg, Idaho, and their mother's refusal to help find them has sparked a nationwide search.
It's also led investigators to reexamine a number of suspicious deaths and events surrounding the children's family.
Here is a timeline of what we know about the case.
July 11, 2019
JJ Vallow's adoptive father, Charles Vallow, was shot and killed by his mother's brother in Chandler, Arizona, at the home where JJ and Tylee were living with the mom, Lori. Charles Vallow had come to pick up JJ.
Alex Cox, Lori's brother, told police he acted in self-defense when he shot Vallow, according to body cam footage released by the Chandler Police Department. Cox also claimed Vallow came at him with a baseball bat after fighting with Lori and that Tylee had tried to defend her mother with a bat, according to the footage.
Cox was not charged in the incident.

KSAV-TV obtained text messages the station said Lori sent to Charles Vallow's sons the next day telling them he had died.
"Hi boys. I have very sad news. Your dad passed away yesterday. I'm working on making arrangements and I'll keep you informed with what's going on. I'm still not sure how to handle things. Just want you to know that I love you and so did your dad!!" Lori wrote to Vallow's sons, according to KSAZ-TV.
But when the sons texted and called Lori to ask what had happened, she waited hours to respond and was not forthcoming about the circumstances around his death, according to KSAZ-TV.
Cheryl Wheeler, Charles Vallow's ex-wife and the boys' mother, told EastIdahoNews.com she was with her son when he received the message.
“I checked the medical examiner’s webpage and found Charles had been killed the day before, and they had it classified as a homicide,” Wheeler told the website. "We further Googled and saw all of the news reports out of Chandler. We found out that Alex (Cox, Lori’s brother) had shot him.”
Colby Ryan, Lori's oldest son, told KSAZ-TV that in August 2019, Lori told him she was moving to start a new job but she didn't tell him where, and then his contact with his mom and Tylee dropped off.
Lori also returned JJ's specially-trained service dog to its trainer.
Neal Mestas recently told Inside Edition that he had trained a Goldendoodle puppy named Bailey for JJ, and the two became very close.
"Bailey just helped him stay calm," Mestas said. "Was a comfort to him as well. One of the things that JJ really struggled with and the family struggled with was him sleeping through the night. He would get up and often times even try and sneak or wander out of the house. And so, when we first introduced Bailey to the home, that was one of the first nights that JJ stayed in his bed and slept through the night."
But Mestas said Lori told him they would be giving the dog back before their move to Idaho. When he inquired further about why they were giving the dog back, he said, Vallow told him it was too hard to talk about.
August is also the last time JJ's biological grandparents, Kay and Larry Woodcock, said they last spoke to him. While JJ used to speak with his grandparents all the time, the last time they FaceTimed with JJ, Kay Woodcock said it seemed like someone else was holding the device and the call lasted less than a minute. The couple never heard from JJ again.
“We don’t know why we weren’t allowed more access to him, but we reached out constantly in every way – email, voicemail, text, phone call, whatever – and never, ever got a response, so that was very concerning to us," Kay Woodcock said during a Jan. 7 press conference.

Lori enrolled JJ at Kennedy Elementary School in Rexburg, the school's principal, Josh Wilson, told EastIdahoNews.com.
Sept. 5, 2019
Lori told JJ's former school, Laurens Institute for Education, also known as LIFE Academy, in Gilbert, Arizona JJ would not be coming back to school this year, according to emails obtained by KTVB.
"Since the circumstances in our lives have changed drastically since my husband passed away last month. I have been offered a job out of state and have had to accept it. we have had to move quickly since the job started asap. so I’m sad to inform you that Joshua won't be returning this year," the email from Lori read, according to KTVB.
Sept. 23, 2019
JJ is last seen at his elementary school in Rexburg, Idaho.
September 23 is listed as the day both JJ and Tylee were last seen in Rexburg, according to the Center for Missing and Exploited Children, but Tylee's aunt, Anne Cushing, recently expressed her concerns to KSL-TV that Tylee could have been missing for longer because she was homeschooled.
"We know when JJ was last seen but nobody seems to know when Tylee was last seen," Cushing told the station.
Sept. 24, 2019
Lori Vallow Daybell unenrolled JJ from Kennedy Elementary School, explaining she planned to homeschool JJ, the school's principal told EastIdahoNews.com.

It was also Tylee's 17th birthday.

In October, two Venmo payments were made from Tylee's account to her brother, Colby Ryan. The memo for one payment on Oct. 16, 2019 is a heart emoji, and the message for another payment from Oct. 10, 2019 reads "we love you."
Colby Ryan previously told KSAZ-TV his mom used Venmo to transfer money within the family.
"My mom is not tech-savvy, so Tylee's account for Venmo was the account she used to transfer money to us," he told the station. Whether Tylee or Lori made the transfers is unknown.
