The mystery of what happened to a missing California hiker deepened over the weekend after police said they received a tip that the woman may have updated her LinkedIn profile.

Police said a caller told them on Sunday that Magdalena Glinkowski, 33, may have made an update to her profile on the professional social networking site since she was last seen on March 30, the San Mateo County Times reported.

Police did not immediately respond to ABCNews.com's request to confirm the report.

The Menlo Park software developer had been unemployed for about two weeks when she went for a hike at Mt. Tamalpais State Park, leaving behind her phone and credit cards in her rental car, Marin County sheriff's Lt. Doug Pittman said.

Glinkowski was last seen on surveillance video near the parking lot. She is described as 5-foot-7, 120 pounds and was last seen wearing a bright pink top, light blue shorts and white and black running shoes.

An air search was launched over the weekend, while more than 80 volunteers and search dogs fanned out across the area looking for signs of Glinkowski.

Anyone with information is asked to contact the Marin County Sheriff's Investigations Unit at (916)473-7265.
