A robbery victim was responsible for Sunday night’s double shooting at a south Lawrence mobile home that left two men with life-threatening injuries, police said.

The motive was among new details Lawrence police released Wednesday about the shooting, which occurred about 11:40 p.m. Sunday at the Easy Living mobile home park, 3323 Iowa.

Officers did not name the two who were shot, but identified them as a 19-year-old Lawrence man and a 20-year old Kansas City, Mo., man. They were taken by air ambulance to a Kansas City-area hospital.

The men “were shot when they were attempting to rob an individual,” police said in a news release. Police said they interviewed the 24-year-old man who fired the shots and recovered the gun he used, but did not arrest him.

A police spokesman said the investigation into the incident is ongoing as officers are waiting to talk to the men who were shot. An update on their conditions was not available Wednesday.

Police said additional people may have been involved in the robbery and they’re seeking more information from the public.
