"Real Housewives of Orange County" alum Tammy Knickerbocker is asking for help in the search for her missing daughter. 

Lindsey Knickerbocker, 34, was last seen on January 9 in Las Vegas after being released from jail for allegedly assaulting an officer for  taking her dog. 

Tammy added that she believes her daughter wasn’t allowed to have her dog at a hotel which prompted the altercation between Lindsey and the cop.

Her mother shared details with Fox News Digital about her last few interactions with her daughter and noted that Lindsey called her from a phone that was borrowed from a "guy on the street."

Tammy said she didn’t recognize the number but received a voicemail message saying, "Please call me. Please call me. I need help."

After the phone exchange, Tammy said she hasn’t heard from her daughter until she received a strange message that she thought was from Lindsey on January 16. 

She got a notification on Facebook Messenger that said, "I’m fine, I’m fine. I’ll call you tomorrow."

Tammy said she didn’t hear from Lindsey the next day. Two days later, she received another "weird" message from a person named Eric saying her daughter was seen in a tent.
