The scammers at the corner of Hacienda Boulevard and Amar Road held up a sign picturing Gabriel Fernandez, a Palmdale boy who was murdered by his mother and her boyfriend in 2013.
The sign requested donations for a boy's funeral.
The Los Angeles County Sheriff's Department received a call about the scammers, who had departed the scene when officers with the Industry Station arrived.
Anyone with information regarding the sign-wielding individuals is urged to call the Industry Station at 626-330-3322.
