A fear of attacks that had rippled through Muslim communities nationwide after the fatal shootings of four men in Albuquerque, New Mexico, gave way to shock and sadness when it turned out the suspect in the killings was himself a Muslim. Prosecutors on Wednesday filed a motion to detain Syed without bond pending trial. "He is a very dangerous person, and the only way to protect the community is to hold the defendant in custody," they said.

A 51-year-old man from Afghanistan was charged Tuesday with killing two Muslim men in Albuquerque, New Mexico, and authorities said he is suspected in the slayings of two others whose deaths sparked fear in Muslim communities nationwide. Officials announced the arrest of Muhammad Syed a day after he was taken into custody.

This year there was a shooting at Albuquerque’s West Mesa High School, killing one student. What was different about this shooting was the use of a ghost gun. Ghost guns are unserialized and untraceable because individual parts and equipment are often sold in kits or printed for at-home assembly. These parts are widely available and can be purchased without a background check. KUNM spoke with Miranda Viscoli, co-president of New Mexicans Against Gun Violence who says these weapons may change how we think about preventing the next school shooting.

Authorities on Monday identified the fourth victim in a series of killings of Muslim men in Albuquerque as the deaths sent ripples of fear through the Islamic community nationwide. Authorities investigating whether the killings are connected said Sunday that they need help finding a vehicle believed to be connected to the deaths in New Mexico's largest city.
