A man who allegedly used an electric scooter to fatally beat a 63-year-old woman on a residential street in Long Beach pleaded not guilty today to a murder charge.

Amad Rashad Redding, 27, is charged in the May 13 killing of Rosa Elena Hernandez, who was attacked in broad daylight in the 3100 block of East 64th Street.

She was pronounced dead at the scene.

“Homicide detectives believe the suspect physically assaulted the victim and then proceeded to utilize a motorized scooter as a weapon during the assault,” police said.

The suspect was seen running westbound on 64th Street following the attack.

About 4 1/2 hours later, detectives took Redding into custody after finding him at a convenience store in the area of Downey Avenue and Artesia Boulevard, a few blocks from the scene of the attack.

Redding is from Louisiana but was living as a transient in Long Beach, according to police.

The motive for the attack is unclear. Prosecutors said they believe it was random.
