TOPEKA, Kan. — Topeka police say a shooting that left two brothers dead was a murder-suicide.

The shooting occurred Thursday in a wooded area near the Kansas River. The dead were identified as 29-year-old Shawn Paul Jacobs and 36-year-old Robert Raymond Jacobs Jr., both of Topeka.

Police spokeswoman Amy McCarter said in a news release the brothers were fishing when both of their vehicles became stuck in mud. A friend who came to help them also got his vehicle stuck in mud.

As the men were trying to get the vehicles free, the brothers began arguing. McCarter says at some point, Shawn shot Robert and then shot himself.
