New Haven saw another shooting within two blocks of Yale’s campus Wednesday.

Two days after the violent mugging behind Pierson College, and less than a week since a shooting at Toad’s Place sent two sent to the hospital, one man was shot in broad daylight at 161 Whalley Ave., the site of the old Shaw’s supermarket, and two blocks from Payne Whitney Gym. An 18-year-old male was shot in his hand through the window of his vehicle Wednesday afternoon. The New Haven Police department Major Crimes Unit has begun investigating the incident, but NHPD Chief Frank Limon said Wednesday night that the department has reached dead-ends on the investigations of multiple recent shootings near Yale’s campus.

“The victims are just not cooperating,” he said, explaining that recent shooting victims have walked into hospitals, received treatment and then refused to answer any police questions.

Yale Police Department Spokesman Steven Woznyk told the News on Tuesday that the department had doubled its patrols in response to a recent rash of nearby violence that now includes five separate shootings, and the muggin earlier this week.

But even with doubled manpower, the YPD must account for shootings that have spanned the northern half of the campus, from near Ingalls Rink and 25 Science Park to the back gate of Pierson College.

“I definitely think New Haven has gotten more dangerous recently,” Hill resident and Gateway Community College student Steven “Smokez” Echols said Wednesday night. “The city is like that because kids have nothing better to do than shoot people.”

Although investigations into many shootings have reached dead-ends, New Haven’s most recent murder — the death of Mitchell Dubey in Newhallville during a home invasion — may soon see an arrest. Limon hinted Wednesday night that the NHPD would announce new developments in the case on Thursday.­
