(CNN) -- Police investigating a triple homicide in a Kansas City neighborhood Tuesday afternoon may have found more clues leading to the person responsible.
A car missing from the homicide scene was found across town the same day, just a few blocks from another crime scene police had been called to investigate.
Authorities are considering the possibility that two crime scenes are related.
"We haven't connected them or linked them, but due to the proximity and the time frame, we can't ignore it either. They could be related." Kansas City police spokesman Tye Grant said at a news conference Tuesday.
The manhunt began after police found five people with gunshot wounds in a southern neighborhood of the Missouri city.
Three people, two females and a male, were confirmed dead at the scene. Two victims remain hospitalized with life-threatening injuries, authorities said.
While witnesses could only describe the suspect as a person wearing a dark hoodie, investigators began searching for a 2002 Toyota Highlander that had been taken from the homicide scene.
Sources told CNN affiliate KMBC that a man stole the car and may have started shooting when witnesses spotted him and attempted to call 911. Area schools were also placed on lockdown after reports of the shooting, KMBC said.
Less than 2½ hours later, officers were called to a separate incident at a Motel 6 across town, where someone had assaulted three guests. No weapon was used, and the suspect fled on foot. While searching the area, police found the Toyota Highlander only four blocks away, according to a news release from the police department.
The close proximity of the missing vehicle to the motel assault prompted authorities to release a description of the suspect, described as a black male in his late 20s or early 30s, about 6 feet 2 inches tall, and weighing about 200 pounds. He was reportedly unshaven, wearing dark pants and a black rag on his head. He was not wearing a shirt and is still at large, authorities said.
Kansas City police said extra officers were on hand at area events and gatherings to provide additional security.
CNN affiliate KMBC also reports that federal authorities have been called in to help investigate.
