Police investigating triple shooting near Downtown Phoenix

Police are searching for a suspect in connection to a triple shooting near Downtown Phoenix.

According to Phoenix Police, the shooting happened just before 5 a.m. on April 6 near 12th Avenue and Madison Street.

Three adults were hospitalized with gunshot wounds. One man has serious injuries and the others, a man and a woman, have non-life-threatening injuries.

Investigators say one of the victims was involved in an altercation with the suspect when the shooting happened.

"From all indications the detectives are getting, it appears that the suspect and victims knew each other," said Sgt. Ann Justus.

People in the area speak out

People in the area say they are now concerned about increasing crime.

"She said no, there's a gun in the planter. I said oh my God, call 911," recounted Joseph Faillace.

Faillace, a local restaurant owner, did not expect such a discovery.

"I was thinking about the shooting this morning that happened at 4:30," said Faillace.

Joel Coplin says he heard the shooting happen.

"Heard three distinct, clear shots that echoed through the place like a canyon," said Coplin, in a phone interview. "10 minutes later, there were, like, five gunshots in the distance, and I said that sounds retaliatory."

"It's scary. I've been here 35 years, always had great business, and now we're surrounded by homeless people," said Faillace. "There's drug addicts, drug dealers, prostitution, there's enforcers. It's scary."
