Albuquerque police have shot and killed a man who they say slashed a good Samaritan's throat.

Deputy Chief William Roseman tells local news outlets the knife-wielding man was attacking a woman when the good Samaritan stepped in to help late Thursday and was stabbed.

Authorities say two officers shot and killed the man after he advanced on police.

Roseman says the good Samaritan is in critical condition, while the woman has been treated and released.

It is the third fatal shooting by the Albuquerque Police Department since the Justice Department released a scathing review of the agency's use of force.

Demonstrators are planning a June march and mock trial of the city's top officer.
