A nurse and a field researcher were among the five people killed and four injured when a pickup truck plowed into a group of bicyclists on a rural road north of Kalamazoo on Tuesday night.

Kalamazoo County Prosecutor Jeff Getting released the names of the victims Wednesday afternoon, according to the Battle Creek Enquirer.

The dead are Debra Ann Bradley, 53, of Augusta; Melissa Ann Fevig-Hughes, 42, of Augusta; Fred Anton (Tony) Nelson, 73, of Kalamazoo; Lorenz John (Larry) Paulik, 74, of Kalamazoo; and Suzanne Joan Sippel, 56, of Augusta.

The four who were injured were taken to Bronson Methodist Hospital and Borgess Medical Center, both in Kalamazoo. They are Paul Douglas Gobble, 47 of Richland; Sheila Diane Jeske, 53, of Richland; Jennifer Lynn Johnson, 40 of Kalamazoo; and Paul Lewis Runnels, 65, of Richland.

Gobble, Jeske and Runnels are in serious condition and Johnson is listed in fair condition, Getting said.

Two of the riders who were killed, Larry Paulik and Tony Nelson, were longtime friends who regularly joined the Chain Gang Cycling Club for Tuesday evening bike rides. They were both members of a Kalamazoo Church -- St. Thomas More Catholic Parish on Monroe Street -- and both believed strongly in advocating for women's ordination in the priesthood, according to a statement from Peace House, a Kalamazoo community group that they were both a part of.

"Larry and Tony carried themselves with a quiet dignity and treated everyone they met with respect," the group said in a statement.

Bradley was a former nurse with Gull Lake Community Schools, and Sippel worked for W.K. Kellogg Biological station, WMMT reported on its website. The station said the two women were friends.

W.K. Kellogg Biological Station, issued the following statement, according to WMMT:
