Stay with FOX 2 for details on this developing story.
Martinez, 20, had been last seen at The Official Movement Closing Party at the Detroit Masonic Temple.
Dani Welchner is a friend of Martinez and she last saw her at 3:00 Tuesday morning.
"I should have kept a closer eye on her," Welchner said.
The problem, was there was a huge after party at the Masonic Temple after the Movement festival ended Monday night.
She said she last saw Grace talking to an older white male, who may have been around 40 years old. He had brown hair and brown eyes, was clean shaven and wearing a blue dress shirt. She said he seemed out of place.
"He was older so he just didn't fit the scene - he looked like a business man maybe - didn't worry me because she didn't seem worried," Welchner said.
At 3:00 a.m., they last spoke. She and Grace agreed to meet up at the car when the party was over at 4:00 a.m. But she never showed. Dani said she waited until 5:30 but still, no sign of her.
She couldn't even call her. The young women left their phones and IDs in the car. So Grace, wherever she may be, has no phone or ID and just a few bucks.
Grace's mother, Betty Martinez has been distributing flyers, making phone calls, checking hospitals, jails, and even the morgue, desperately searching for her youngest daughter.
