MDOT announced on Twitter that westbound I-94 was closed around 10: 15 a.m. Roughly 15 minutes later, MSP also tweeted about the road closure and offered more details.
According to MSP, the interstate is closed so officers can search for a shell casing for a shooting that happened on the freeway last week.
Around noon, the interstate was reopened. It's not known if police found what they were researching for.
