According to a police officer, the suspect, who committed suicide on Friday, shot more than 20 bullets.

Authorities said Friday that a suspect in a shooting in Washington, D.C. that injured four people used a “sniper-type setup” and fired more than 20 bullets.

According to Metropolitan Police Chief Robert Contee, the guy is suspected to have committed himself as police from the Metropolitan Police Department were entering an apartment where he was at the time.

It was unclear whether the suspect was Raymond Spencer, 23, who had been designated as a subject of interest by officials previously. Authorities are no longer looking for Spencer, according to Contee, but he won’t name the suspect until his family is told.

According to Contee, the suspect opened fire from an apartment on Connecticut Avenue on Friday afternoon while holding a tripod.

Authorities discovered several rounds of ammunition and six firearms, including long guns and pistols, at the property, he added.

“Clearly, his objective was to murder and injure people of our community,” Contee said to reporters.

He went on to say that a probable motivation was yet unknown.

At least three people were killed in a shooting in the city’s Embassy Row neighbourhood on Friday, according to police, but a fourth was subsequently reported to cops on the site.

Assistant Chief Stuart Emerman said three of the victims — a 12-year-old girl who was shot in the arm, a woman in her mid-30s, and a 54-year-old man — were stabilised.

He claimed a woman in her mid-60s was treated and released at the scene after suffering a graze cut to her upper back.
