The bank robbery suspect turned herself into police headquarters, before being turned over to the FBI.
"She did notice the heat was on," said Lt. Michael Shaw, Michigan State Police. "Scantavia became very aware that the state police was looking for her and she knew she was running out of options."
Police say Isaac was wanted for her involvement in at least eight credit union robberies in a three-month period in Lansing, Livonia, and Ann Arbor late last year.
Crime Stoppers of Michigan was offering a $1,000 reward Wednesday for Isaac. Her photos were seen on FOX 2.
Isaac is now in custody awaiting federal charges.
Her six-person crew police say was responsible for the robbery in Marysville which police catching the people believed to be in her crew in December.
"One of our hometown security teams was able to get them on the way to robbing another bank," Shaw said. "She just happened to no go along with them on that particular excursion."
Police say Isaac's brother was the ringleader, 18-year-old Angelo Mitchell of the group, which wore wigs and makeup and passed notes to tellers demanding money and threatening to kill them if they didn't comply.
FOX 2 stopped into what Scantavia Isaac lists as her former employer on her online resume, American Tax Services in Detroit.
One employee's response to hearing Isaac's name was "What did she do now?" before saying that she doesn't know " A Scantavia Isaac."
Isaac's resume shows she's done everything from preparing taxes to styling hair and working at Eastpointe's Nails Palace.
"I'm just shocked," said Tara Berry, a former co-worker at Nails Palace. "She was a very sweet person, very dependable, reliable. Great personality. I could not believe it."
