On Friday police made another public plea, participating in a two-hour call-in special on Univision called "Voices of Maryvale," during which they encouraged viewers to report any and all tips.
"At this point, we're hoping to get a tip or something that somebody can give us that we can follow up on and hopefully lead us to this person before he hits again," said Lt. Ed DeCastro.
Also participating in the special was Phoenix City Councilor Daniel Valenzuela, Silent Witness and some of the murder victims' family members.
"We're hoping this helps," said Susana Castro. "We're looking at it as part of our grief process to have this person stopped because this can't happen anymore. It's already been seven people."
