A Kalamazoo museum is opening its doors as a place of reflection and peace for those affected by the killing of six people in and around the city.

The Kalamazoo Institute of Arts is waiving its usual admission fee for the rest of the month following last weekend's attacks.

Executive Director Belinda Tate says in a statement that the museum wants to "open our doors to share the peace and beauty of the museum."

Tate says the museum is being offered "as a respite space for reflection, nourishment and quality time with family and friends."

Authorities say the shootings by Jason Dalton were random and they haven't revealed a motive. The shootings occurred in a restaurant parking lot, outside an apartment building and at a car lot.

Western Michigan University officials say they will improve how the school communicates during emergencies after it didn't issue an alert during the series of weekend shootings a few miles from campus.

The Kalamazoo school's leaders heard from dozens of students Monday night, including some who criticized the school's response or who had ideas about improving the alert system.

University President John Dunn says the alert system is set up to warn of threats to the campus and people on it. However, the Kalamazoo Gazette reports (http://bit.ly/1Qe9sLk ) that Dunn apologized, saying the school "did not meet your expectations."

The school's public safety chief, Scott Merlo, says there was a "breakdown in communication."

An Uber driver has been charged in the attacks, which killed six people and wounded two others.

More details are emerging about the night authorities say a Michigan man has admitted gunning down six randomly chosen victims in and around Kalamazoo. But any hint as to why remains stubbornly elusive.

Authorities allege Jason Dalton carried out the attacks over hours during which he also ferried passengers around town as an Uber driver. The 45-year-old appeared briefly in court by video link and was charged Monday with six counts of murder.

Kalamazoo police Det. Cory Ghiringhelli told the court Dalton admitted to investigators "that he took people's lives."

The admission seemed only to deepen the mystery of what was behind the killings of six people with no apparent connection to the gunman. Police and prosecutors acknowledge a motive may never be fully known.
