Police are seeking to identify and speak with a male person of interest as part of their investigation into the shooting deaths of Stephen and Djeswende Reid in Concord, New Hampshire, last month, authorities announced Tuesday.
A sketch of the person of interest was also released Tuesday. The man is described as being in his late 20s or early 30s, approximately 5'10" tall, with a medium build and short brown hair.
Stephen Reid, 67, and Djeswende Reid, 66, left their apartment complex on April 18 and went for a walk toward some trails. The husband and wife were reported missing after Stephen didn't show up at an event.
Their bodies were discovered the night of April 21 in the area of Broken Ground Trails. An autopsy found both died of multiple gunshot wounds.
The person of interest was seen in the vicinity of the shooting incident on April 18 wearing a dark blue jacket, possibly with a hood, khaki-colored pants, and he was carrying a black backpack.
The reward for information leading to an arrest has also been increased to $33,500. Twenty thousand dollars of that amount was donated by an anonymous donor who has pledged the funds only for those who come forward with information in the next 60 days.
Anyone with information about the identity of the person of interest or his whereabouts is asked to contact the Concord Police Department at 603-225-8600. Tips can also be submitted anonymously to the Concord Regional Crimeline website at www.concordregionalcrimeline.com or by texting TIP234 and your message to 274637.
At a news conference Tuesday, investigators stressed that the person of interest could be a witness or a suspect -- they want to speak with him, though Assistant Attorney General Geoffrey Ward noted that anyone who thinks they know the man is asked to contact police, rather than reach out to him.
Asked about what the image was based on, Ward wouldn't get into details, saying only, "It's a depiction that we are confident enough in to bring to your attention."
He didn't discuss the motive or whether the couple was targeted, saying he wanted to protect the investigation.
Police said earlier this month that they had received over 100 tips in the case -- Ward said some have "certainly" been helpful. The FBI has also joined the investigation.
So far, no arrests have been made in the case. It remains unclear who shot the couple and what their motive might have been.
"We continue to encourage vigilance for folks that live in that area," Ward said, noting that investigators have no indication of any specific threats but suggesting residents take steps like locking their doors.
Investigators say the couple moved to Concord just three years ago, as it was Stephen's hometown growing up. Police said they were avid outdoors people, known to take frequent walks along the trails near their home.
Concord Police Chief Joseph O'Connor said the investigation has been exhausting but credited his staff with working well.
"I think the city of Concord is a safe city; it's the safest state in the country. I still think Concord's safe no matter where you go," O'Connor said.
The investigation is ongoing, the attorney general's office said, and additional information will be released as it becomes available.
