Around 11:50 p.m. Monday, Long Beach, Ind., police responded to a call about a man who was unconscious at the beach after being beaten, according to Long Beach Police Chief Marshall Robert Sulkowski. On arrival, police found Kevin Kennelly Jr., 17, lying on the ground, unconscious, with several people standing around him.

Kennelly, of the 9900 block of South Damen Avenue, was taken to St. Anthony Hospital in Michigan City, and later flown to St. Anthony Hospital in Crown Point, due to the severity of his injuries.

He died just before 11 a.m. Wednesday, according to the Lake County (Ind.) Coroner’s office. An autopsy was scheduled for Thursday.

Meantime, an arrest warrant has been issued for another Chicago resident — 19-year-old James K. Malecek — who is charged with involuntary manslaughter, aggravated battery, and battery, according to Sulkowski.

Chicago Police, the U.S. Marshal’s office and Illinois authorities are assisting Long Beach Police in the search for Malecek, according to Sulkowski.

Police said Kennelly intervened in a fight on the beach on Monday. Malecek allegedly hit Kennelly in the head during the fight.

Kennelly attended Mount Carmel High School, where he would have been a senior this fall and where was on the varsity baseball and soccer teams.

His father, Kevin Sr., is a Chicago Fire Department captain who survived a fall in May 2009, when a set of stairs collapsed under him and another firefighter while battling a fire in the Englewood neighborhood.

According to the Mt. Carmel website, visitation for Kevin Jr. will be held from 4 p.m to 8 p.m. on Friday at Mount Carmel Convocation Center, 6410 S. Dante Av.

A funeral will be held Saturday at 10 a.m. at St. Barnabas Parish, 10134 S. Longwood Dr., followed by burial at Holy Sepulchre Cemetery in Alsip.

In lieu of flowers, donations can be made in Kevin’s name to Mount Carmel High School.
