"I don't tweet often but sometimes my tweets come true so, together let’s manifest on twitter that Naya will be found safe and sound!!" she wrote.

"I want to Thank 100+ Volunteers, Police & everyone who are helping in Naya's recovery efforts," he tweeted. "Please, keep looking for her. Bring her home, please."
The Ventura County Sheriff's Department began a rescue mission for Rivera on Wednesday, after her son Josey was found asleep and alone on a pontoon boat in Lake Piru. On Thursday, that mission was shifted to a "recovery operation," as Rivera was presumed dead.
During a press conference, they said there were "no sights of foul play" and said her disappearance appeared to be "a tragic accident."
They added that their goal was to bring "Ms. Rivera home to her family so that they can have closure."
