A man suspected of shooting and killing eight people in suburban Chicago fatally shot himself after a confrontation with law enforcement officials in Texas, police said late Monday. Police in Joliet, Illinois, said on Facebook that at about 8:30 p.m. Central time 23-year-old Romeo Nance was located by US Marshals near Natalia, Texas, and that Nance shot himself after a confrontation. The Medina County Sheriff's Office in Texas said on Facebook that the agency received a call about a person suspected in the Chicago killings heading into the county on Interstate 35.

A standoff then occurred between Nance and police from multiple agencies at a gas station, where Nance shot himself, the sheriff's office said. Nance is suspected of fatally shooting eight people at three locations in the Chicago suburbs, sparking a search that left neighbors on edge earlier Monday as police warned he was still on the loose and should be considered armed and dangerous. Police in Will County in Illinois and Joliet previously said they did not know of a motive for the killings, but said Nance knew the victims.

The FBI's fugitive task force had been assisting local police in the search for the suspect, Joliet Police Chief William Evans said. According to authorities, Nance was related to most of the victims and is believed to have first shot seven people at two relatives’ homes in the city of Joliet on Sunday. Police said they had not yet determined the victims’ exact relationships to Nance. The Illinois authorities provided a clearer timeline of the shootings on Tuesday, saying they believe all eight people killed and a ninth person wounded were shot Sunday and Nance fled the area by that evening.

But they told reporters there is no evidence of a motive yet for the killings. The Will County coroner on Tuesday identified the victims found at the Joliet homes: 38-year-old Christine Esters, 47-year-old Tamaeka Nance, 35-year-old William Esters II, 31-year-old Joshua Nance and 20-year-old Alexandria Nance. The names of two teenage girls, 14 and 16, were not released. Authorities previously identified the man killed outside the apartment building as Toyosi Bakare, a 28-year-old man originally from Nigeria who had been living in the U.S. for about three years.

Nance fatally shot himself Monday evening after U.S. Marshals located him near Natalia, Texas, about 30 miles (48 kilometers) southwest of San Antonio and more than 1,000 miles (1,690 kilometers) from Joliet, authorities said. He had no known ties to Texas, Illinois authorities confirmed Tuesday. The Texas Rangers are investigating Nance’s death and believe he shot himself, said Lt. Jason Reyes, a spokesperson for the Texas Department of Public Safety, of which the Rangers are part. Reyes said he could not provide any other information about the circumstances of Nance’s death or his confrontation with law enforcement officers.
