STATEN ISLAND, N.Y. -- The 120th Precinct took to the Twittersphere Monday night to distribute photos of dirt bike riders wanted for questioning in the shooting of a couple in New Brighton on Sunday.

These individuals r wanted for a shooting that occured on Jersey St. Anyone with info please call 1800577TIPS #120PCT pic.twitter.com/nDD0BgSTSw — NYPD 120th Precinct (@NYPD120Pct) May 5, 2015

The array of photos on a "Wanted" flier show four individuals riding dirt bikes together down the street.

The NYPD's Deputy Commissioner of Public Information's office had previously said that two suspects were sought in the shooting, but the flier singles out a lone "perpetrator riding a dirt bike," who "intentionally discharged multiple rounds from a firearm striking two victims."

The shooting, which occurred at 5:37 p.m. Sunday in front of 224 Jersey St., injured a couple who were standing on their front stoop.

The victims, Pat Vamosy-Schmidt, 63, and her husband, Ed Schmidt, 71, were taken to Richmond University Medical Center, West Brighton, with gunshot wounds to the right forearm and abdomen, respectively, according to police.

A RUMC spokesman said Tuesday that Ms. Vamosy-Schmidt was in stable condition and that her husband was in critical but stable condition.

Neighbors do not believe the couple, who are longtime New Brighton residents and beloved members of the community, were targeted by the gunman. Police have said that the motive for the shooting is not known.

North Shore City Councilwoman Debi Rose visited the scene of the shooting Sunday night and returned Monday with police and volunteers to distribute fliers seeking help from residents.

Anyone with information about the shooting should call Detective Richard Dinkle at 718-981-2714, Detective Borough Staten Island at 718-876-8196 or the NYPD Crime Stoppers hotline at 1-800-577-8477(TIPS).
