Police looking for 25-year-old Jessica Heeringa who disappeared from her job at a west Michigan gas station last month say they're investigating high-priority tips received over the weekend.

Details weren't released, but Norton Shores Chief Dan Shaw said "every piece of information we get is beneficial."

Shaw said there are a "couple tips" about the case that have been actively investigated.

Heeringa disappeared April 26 before she was set to close a gas station in Norton Shores, near Muskegon. Her purse and other personal belongings were found at the convenience store.

Police said there was no indication of a robbery. A task force is investigating.

The Norton Shores police department earlier announced blood found outside the gas station belonged to Heeringa.

Police have released a description of a silver minivan and a man seen in the area.

Investigators ruled out a number of family members, friends and persons of interest.

In the wake of the disappearance, state lawmakers have said they are considering whether to require video cameras at convenience stores and gas stations.
