She vanished without a trace from the home she shared with her son on February 12, 2014. Police said they are stumped and have no suspects. She would have been 56-years old this past Wednesday.

Some of the Gonzalez’s siblings gathered outside North Miami Police headquarters on Friday afternoon to ask again for the public’s help and to remind everyone that there is still a $10,000 reward in this case.

“To me she meant the world,” said Noemi’s brother David Gonzalez, as he fought back tears. She always took care of my mother and father.”

David Gonzalez, who is from North Bergen, New Jersey, told CBS4’s Peter D’Oench, “It’s important for us to get some answers. It is heart wrenching not knowing where one’s siblings are. We were a very close family. I would give anything to find her. I will never give up until I get some answers. We just need to have some answers.”

Noemi Gonzalez’s son Pedrito told police he last saw his mother at 2 a.m. when he went to check on her at their home at N.E. 4th Ave. and N.E. 136th St. . He told police that when he got up at 8 a.m., she was gone.

She left behind her pocketbook, keys, cell phone and medicine for epileptic seizures.

Noemi’s sister, Maria, from North Miami Beach, said, “We don’t believe that she vanished like that. We need to find her. We don’t know where she is or where she has been or what happened to her. She’s part of us.”

Liz Gonzalez, who is from North Bergen, New Jersey and who is Noemi’s sister-in-law, said, “Our purpose is not to give up. There is no other option. Not to have Noemi is devastating to this family. We can’t stop looking for her. We are not going to give up. We have faith. And God will answer. We will find her. We want her to come home to us.”

“Someone must know where she is,” she said. “There is no way she just vanished. Our plea is to get some information that will lead us to Noemi.”

She said Noemi’s loved ones planned to make a stop at a Walmart store on Saturday that Noemi used to go to and talk to shoppers and possibly pass out flyers.

The lead detective, Sgt. Joseph Kissel, said, “We don’t know what happened to Noemi. We are baffled by this entire case since she went missing. Her home was not in disarray. There were no signs of foul play. We don’t have any answers or suspects. We need people to call Crime Stoppers and give us whatever help they can.”
