An Arizona man has been arrested for allegedly strangling a 41-year-old woman passenger on a city bus last Friday, police said.

Diane Craig was found unresponsive with a bag strap around her neck on a Pheonix city bus Friday morning, May 6. She was taken to a hospital where she died from her injuries later that day.

Phoenix police detectives determined Diane had been strangled to death at some point on the bus ride.

The alleged killer, 26-year-old Joshua Bagley, who boarded the bus separately, was seen on surveillance footage,  strangling Craig with bag straps and pushing her to the ground, police said in a news release Before getting off outside of a QuikTrip, Bagley took several items from Craig. 

"He robbed our family. He did, he robbed our family," said Shontae Vinson, Craig’s cousin. "She was like the life of the room."

 Bagley is currently in police custody as the booking and interview process is completed, according to police

"Throughout the course of the investigation, detectives were able to gather enough evidence to name Joshua Bagley a suspect in her death," Sgt. Vincent Cole told People.

Investigators haven’t reported any information as to what led up to the murder.

"Diane was a wonderful person. She was so full of life," Roshuanda Boss, one of Craig's cousin, told the outlet.

"She definitely did not deserve this. Our family is hurting." "He did this to our family. He can do it to someone else. We need this guy off the streets," said Boss.

Craig’s family has launched a GoFundMe page to meet with funeral expenses.

"Hello everyone, my name is Edward and Diane Craig was the victim of the Phoenix bus strangulation," the GoFundMe reads. "She is my oldest daughter and I need help with her home going plans. It was an unexpected tragedy (for) me and the family."
