A pedestrian who was injured Saturday night while trying to cross 23rd Street was in critical but stable condition Monday at a Kansas City-area hospital, a Lawrence police spokesman said.

Sgt. Matt Sarna Monday identified the injured man as 28-year-old Jeffrey A. Brown of Lawrence.

Police said that about 8 p.m., Brown was trying to cross 23rd Street, heading south, near the Iowa Street intersection when he was struck by two eastbound vehicles.

Accident investigators Monday were still trying to determine exactly where Brown was when he tried to cross the street. But Sarna said the preliminary investigation indicated eastbound traffic had a green light, meaning a pedestrian crossing to the south would not have had a walk signal.

Joseph Henderson, who was stopped in traffic, told the Journal-World Saturday night that a man appeared to be attempting to climb over ice in the small island between the turn lane and westbound lanes of 23rd Street when he slipped and appeared to fall. Henderson said the man continued to try cross the street when one car narrowly missed hitting him before he was struck by another vehicle.

Sarna said Brown was struck by a 2005 Chevrolet Impala in the inside lane and then a 1997 Chevrolet pickup truck in the outside lane of eastbound 23rd Street. Both drivers stopped, he said, and people began administering aid to Brown before medics arrived. Brown was flown to the hospital by helicopter ambulance, which had landed in the parking lot of Hobby Lobby, he said.

Sarna said officers were still trying to determine if alcohol or anything else was a contributing factor. He said police were also trying to determine where Brown had been immediately before the accident and asked anyone with information to call Douglas County Crime Stoppers at 785-843-TIPS (8477).

No citations had been issued as of Monday, Sarna said.
