He added: "This is such a tragic situation & our hearts go out to the MSU community, all of Lansing and East Lansing!"

Johnson starred at his hometown school for three years before he was the first overall pick in the 1979 NBA Draft – he won the national title just a few months before, and his number 33 is retired by the university.

Former Spartans running back Le'Veon Bell also sent a message on Twitter. Bell played at Michigan State from 2010 to 2012, and was drafted the next year.

New Phoenix Suns owner Mat Ishbia won a national championship with the Spartans in 2000, and had a similar sentiment as other alumni.

"Deeply saddened by the horrific tragedy that took place at Michigan State University last night," he wrote. "Sending my love, thoughts, and prayers to all MSU students, the university, and the entire Spartan family.
