DAYTON, OH- Dayton's year of tragedy continued Tuesday as city officials held a somber news conference to update the condition of a police detective shot twice in the face while attempting to serve a search warrant at a home as part of a drug trafficking investigation.

Thirty-year veteran officer Jorge DelRio remained in critical condition, his chief describing the injuries as grave.

"2019 has been an especially difficult year for our police department," City Manager Shelley Dickstein said at the news conference. "The extraordinary number and frequency of tragic events have fallen squarely on their shoulders."

This is what officials said happened just before 7 p.m. Monday at a house on Ruskin Road: Det. Jorge DelRio came to conduct the search as part of a DEA task force. He announced he was an officer but got no answer. He went inside, went to the basement, and a gunman opened fire.

"His injuries are grave, he was struck twice in the face, and those bullets penetrated deep. So his condition is grave," Police Chief Richard Biehl said.

There were five people inside the house when officers arrived. Three men were arrested. A juvenile was also detained.

Police said they also found cash guns and fentanyl when they searched the house. Officials called it an assault on the Dayton community that is still healing from a mass shooting just months ago and the Memorial Day tornadoes that ravaged the region.

None of the suspects were hurt during the arrests, police said.

The man suspected of shooting DelRio has been charged with assaulting an officer with a deadly weapon and two other men who were charged with conspiring to distribute drugs, including fentanyl.

Prosecutors say the four arrested for their crime could face 20 years to life in prison for what happened here.
