A New Mexico State Police officer was shot and killed and several other officers were injured in a shooting on Thursday on Interstate 10 between Deming and Las Cruces, N.M., the authorities said.

A suspect was dead, the State Police said in a statement, adding that the “scene is still active with limited information.” The interstate was closed, the police said.

The authorities said they were investigating two shooting scenes along the highway.

Ami Evans, a spokeswoman for the New Mexico Department of Transportation, said that the officer had been killed after the first shooting on Interstate 10 near Akela, between Deming and Las Cruces. From there, a vehicle drove east on the highway through Las Cruces, about 40 miles away, where another officer was shot near Avenida de Mesilla and taken to the hospital, she said.

Dan Trujillo, a spokesman for the Las Cruces Police Department, said his agency had been called to help after the first shooting and had blocked off exits along the highway, as officers followed a white truck.

The Las Cruces Police Department confirmed that officers from several agencies were investigating an “incident involving shots fired” along the interstate.

The department said that drivers should avoid the area and seek alternate routes until the investigation was complete, a process that could take hours.

The Doña Ana County Sheriff’s Office asked people to avoid the area of Interstate 10 near the Interstate 25 interchange and Motel Boulevard. The sheriff’s office said that lanes of traffic had been shut down in both directions and closed for several hours.
