An Ohio police officer was shot and killed after being ambushed by a gunman, authorities said

A suspect accused of fatally shooting a police officer near Cleveland on Saturday evening is dead, authorities said Sunday.

Officers were dispatched to a home in Euclid, Ohio, just before 10 p.m. when a caller said she and her child had been threatened by the child’s father, Euclid Police Chief Scott Meyer said Sunday.

When police officers checked the backyard, they were “assumed by gunfire,” Meyer said.

Officer Jacob Derbin was shot and taken to a hospital but died from his injuries later that night, police said. No other officers were injured, Meyer said.

The suspect was found dead in a home in Shaker Heights, Ohio, on Sunday, authorities said. Law enforcement officials would not elaborate on the suspect’s cause of death or say whether there was an exchange of gunfire between officers and the suspect.

Meyer said tactical teams were on scene for hours and the suspect, identified by CBS affiliate WOIO as 24-year-old Deshawn Anthony Vaughn, was unwilling to leave the home. According to authorities, no one was injured on Sunday.

Shaker Heights is approximately nine miles south of Euclid.

Derbin, 23, was a military veteran and had been on the force for less than a year, according to Meyer. Derbin is engaged and will get married in July, Meyer said. According to Meyer, his father is also a Euclid police officer.

“The Euclid Police Department asks that you keep the fallen officer, his family, loved ones and our agency in your thoughts and prayers,” Euclid Police Department Capt. Mitch Houser said in a news release.

“Multiple law enforcement agencies” were involved in the search for the person responsible, Houser said.

Residents who live on the street where the incident occurred said they remembered hearing about a dozen gunshots, NBC affiliate WKYC reported.

Meyer described the slain officer as “an amazing human being” with “a big heart” and “an incredible smile.”

“The world is a better place with him,” Meyer said.

Mayor Kirsten Holzheimer Gail said in a statement on Sunday: “We are struggling with a deep sense of sadness and disbelief.” The mayor called on the community to “come together in solidarity and support, not just to honor a hero who selflessly sacrificed us served and protected, but also to give strength to one another in this time of grief.”
