DALLAS — Police have confirmed an arrest warrant was issued for a Grand Prairie man who was reported missing, along with his girlfriend of eight years, 26-year-old Weltzin Garcia Mireles.

According to authorities, a warrant for 28-year-old Alfonso Roderick Hernandez was issued a few weeks ago in connection to an assault involving Weltzin, who then filed a restraining order.

Meanwhile, authorities are searching for both Weltzin and Hernandez, whose vehicle was found in the White Rock Lake area in Dallas. The couple have two children, a 6-year-old girl and 3-year-old boy, who are currently with the missing woman's twin sister. 

According to a Facebook post made by Weltzin' sister, Atziry G. Mireles, the couple "disappeared" at about 1:30 a.m. Tuesday. The missing woman's cellphone last pinged in the White Rock Lake area, where Hernandez's vehicle was later found. 

"Police dogs and helicopters haven't find [sic] anything," Atziry wrote about their search around White Rock Lake. "We're thinking they took off in another car, maybe Uber. She might be in danger!!!"

Atziry also said Hernandez sent a goodbye text message to some family members prior to their disappearance.

Family and friends say the couple planned a birthday party for their 6-year-old daughter Sunday but canceled it and instead planned a visit to Traders Village.

A Facebook page called "Help Us Find Weltzin" was set up Tuesday night and continues to post updates on the family's search. Posts on the page also urge people to use #HelpUsFindWeltzin when posting about the search via social media.
