A 17-year-old St. Charles boy is charged with possession of an incendiary/explosive device and discharge of a firearm or dangerous weapon endangering public safety, Winona Daily News reports. The teen is accused of making a pipe bomb that was discovered in his mother's trunk last week while he was a patient at the hospital in Rochester. Authorities say the 3-foot-long device weighed about 50 pounds with gunpowder and fireworks.

The Mayo Clinic hopes its plan for a new cancer network will bring medical care closer to where patients live. Its first partner is the Coborn Cancer Clinic in St. Cloud, which will have access to Mayo doctors and resources.

Labor officials say Mayo discriminated against an employee who made legally protected complaints about safety issues. The Post-Bulletin says James Seehusen shared concerns with supervisors about a vehicle's safety as well as the company's failure to conduct regular inspections. Supervisors later suspended Seehusen, a move they say was unrelated to his complaints, but the judge said Mayo failed to prove that.

The Federal Aviation Administration and the National Transportation Safety Board are investigating a helicopter crash that killed two Mayo Clinic employees in Florida. The Star Tribune reports the two Jacksonville hospital employees were flying to the University of Florida Monday to retrieve organs. A spokeswoman with the FAA says neither the employees nor the pilot survived after crashing northeast of Palatka, Florida.

Officials with the Winona County Sheriff's Office tell the Associated Press they are seeking an arrest warrant to take a 17-year-old suspect into custody. Authorities say the teen was at the hospital in Rochester when the pipe bomb was discovered in the trunk of his mother's car last Thursday. It was safely detonated and no was hurt. The teen allegedly made the 3-foot-long pipe bomb in Winona County.

The project includes adding two stories to its Florida hospital and a separate primary clinic. Construction is set to begin next month and be complete in about two years.
