(CNN) -- The governor of Missouri on Sunday ordered the deployment of 25 National Guardsmen to help search for an infant girl missing for nearly two weeks.
The members of the Missouri National Guard's 1139th Military Police Company, based in Harrisonville, will spend one day in Kansas City to help local and federal authorities look for 11-month-old Lisa Irwin.
On Friday, a private investigator working for the family said two anonymous benefactors had offered a $100,000 reward for Lisa's safe return.
Police, who were joined in their search effort by federal authorities last week, have said they have no suspects or solid leads in Lisa's disappearance.
The girl's family announced Tuesday that they had brought in Bill Stanton, a prominent private investigator, to help with the search -- a high-profile twist in a case that has drawn national attention.
Lisa was last seen around 10:30 p.m. October 3, asleep in her crib, police said. Authorities were called to the home about 4 a.m. October 4.
Lisa's father, Jeremy Irwin, told reporters that he discovered the girl was missing when he got home from work.
Three cell phones were also reported missing at the home, Young said.
Lisa is described as 30 inches tall with blue eyes and blond hair, police said. She weighs between 26 and 30 pounds and was last seen wearing purple shorts and a purple shirt with white kittens on it.
The missing girl has two bottom teeth and a "beauty mark" on her right outer thigh. She had a cold with a cough at the time of her disappearance, police said.
