LAKE LOUISE, AK (WRCB) -- A pair of brothers from Cleveland on vacation in Alaska perished in a boating accident near Lake Louise Friday afternoon.

According to the Mat-Su Valley Frontiersman (http://bit.ly/LdGLZ6), brothers Steven Kirkpatrick, 59, and Jeffrey Kirkpatrick, 56, fell out of their rented 14-foot boat.

Tim DeSpain with the Alaska State Patrol said the investigation determined that the four men in the group were trying to restart the boat when one of the brothers fell in the water.

The other brother dove in, but was unable to save his sibling.

The two other men in the group, Edwin Curtis and Rex Calfee, were able to get Steven back to shore, but their attempts to revive him using CPR were unsuccessful.

DeSpain confirmed that Jeffrey's body was recovered from the bottom of Lake Louise after being submerged for approximately 45 minutes.

Neither brother was wearing a life jacket, according to a statement from the ASP.

The wilderness area, about 170 miles northeast of Anchorage, is a popular sporting destination during the summer months.
