ROCHESTER HILLS, Mich. — Authorities on Sunday identified the man who opened fire at a splash pad in suburban Detroit before taking his own life, but his motives remained unknown as investigators worked to determine if he left behind any hint of his plans.
Oakland County Sheriff's spokesperson Stephen Huber said the shooter was 42-year-old Michael William Nash of Shelby Township. Sheriff Mike Bouchard said Saturday evening that the gunman had no prior criminal history but apparently suffered privately from what the sheriff called ''mental health challenges.''
''It's our understanding that he was undergoing some mental health challenges, but no one that we know of was notified,'' Bouchard said during an evening news conference.
The splash pad shooting was one of at least four mass shootings that took place around the country Saturday night and early Sunday morning. Six people were shot in a residential neighborhood in Lathrup Village, another Detroit suburb. Seven people were shot at a party in Methuen, Massachusetts, and eight people were shot during a Juneteenth celebration in Round Rock, Texas. Two people were killed in that shooting.
Authorities said Nash drove to suburban Rochester Hills on Saturday and opened fire at a splash pad in a city park around 5 p.m. A splash pad is a recreational area with a nonslip surface where people can play in fountains and water sprays.
The sheriff said Nash fired as many as 28 times, stopping several times to reload.
In the chaos, ''people were falling, getting hit, trying to run,'' Bouchard said. ''Terrible things that unfortunately all of us in our law enforcement business have seen way too much.''
The gunman was ''apparently in no rush. Just calmly walked back to his car,'' the sheriff said.
