KANSAS CITY, Mo. -- Police may have found a new lead in last week's triple homicide in Midtown.

On Aug. 17, two women -- one of whom was seven months pregnant -- were shot multiple times while they were sitting in a parked car near Walnut Street and Armour Boulevard.

Ashley M. Tyler-Stewart, 21, and Alisa R. Winrow, 19, were pronounced dead at a local hospital. Doctors delivered Tyler-Stewart's baby boy, but he died after 47 minutes, police said.

Investigators said crack cocaine was found in the car and on Tyler-Stewart.

KMBC reported that William Stewart, the husband of Tyler-Stewart and the baby's father, has been searching on his own for the shooter.

Police said there is still no suspect in the case, but officers said they think Stewart can help them solve it. Officials said they believe the women were shot because of a drug turf war and that Stewart was involved in the drug activities.

Police said Stewart was wanted in connection with an assault that happened several hours after the shooting.

"It appears that he was looking for an individual that probably killed his wife and unborn child and also another friend," Officer Darin Snapp said.

Police said Stewart went to a home on East 43rd Terrace to look for someone named Roach Clip. Stewart is accused of holding a gun to a woman's head at the home and trying to get her to call Roach Clip. Police have since found him.

"We had talked to that person, and we do not believe that he was involved in the triple homicide," Snapp said.

Police said Stewart also visited another house after the shooting to look for suspected drug dealers.

Thursday, police said the 30-year-old Stewart was taken into custody in Crawford County, Ark., after allegedly leading police on a high-speed chase on Interstate 40. Officials said it began as a routine traffic stop for a dangling rear license plate, but police said Stewart showed a fake identification card and then sped away.

Investigators said a second man was in the car and that a gun was tossed from the vehicle during the chase. The car ended up in a ditch, and both men were arrested. The other man was identified as Robert Thompson, 32.

Officials said they traced Stewart to Arkansas by his cell phone.

Police said Stewart is not a suspect in the Aug. 17 shooting, but officers said they suspect that Stewart may know who did it.

Friday, Kansas City detectives went to Arkansas to talk to Stewart. Investigators said they want Stewart to tell them what he knows about the shooting.

"Hopefully, we can get a name from him and finish our investigation. We believe strongly that he knows who killed these three people," Snapp said.

"My feeling is, he needs to come forward and give any additional information that he can instead of running and hiding. William, you need to come over here and find out what's going on," said Anthony Tyler, the victim's uncle.

Tyler-Stewart's grandfather told KMBC that Stewart called him crying earlier this week, saying he felt guilty about the homicide.

Stewart has outstanding warrants, and police said that may be why he fled.

Stewart is being held on $100,000 bond and is awaiting extradition to Missouri.
