"A deceased female has been discovered along the railroad tracks in south Orange County by [a] mounted unit," Orange County Sheriff's Office Capt. Angelo Nieves told AOL News.
Investigators have been searching for Michelle DuBois, 36, since Monday evening, when her husband, Chris DuBois, contacted police and reported her missing.
Chris DuBois said he and his wife had gotten into an argument earlier that morning. He said he last saw her when he left their Nela Avenue home to take their twin boys to day care. He was gone for about 45 minutes, and when he returned his wife was gone, he said.
Her wallet, keys and cell phone were found inside the home, and her vehicle was still parked in the couple's driveway, police said.
Investigators searched the DuBois home and were seen removing several items. Dogs trained to sniff out cadavers and their handlers were also seen searching the perimeter of the home and surrounding area, Central Florida News 13 reported. Authorities reportedly have found no signs of foul play.
Earlier today, teams of searchers were dispatched to the area, along with a mounted patrol from the Orange County Sheriff's Office. Authorities reported finding the body shortly before noon, but have not made a positive identification.
According to WFTV, neighbors said Michelle DuBois has been suffering from bouts of depression since the birth of her children. Authorities have not confirmed that report but have said that prescribed medications that she needs were found inside the home.
Calls made by AOL News to the DuBois house were not answered today.
Chris DuBois has not been called a suspect or person of interest in his wife's disappearance. The investigation is ongoing, and authorities said they expect to release more details later this afternoon.
