Here is what we know about the incident:

How did the shootout in Allen, Kentucky, start?

Officers went to Storz's house on Main Street in Allen, which is 15 minutes from Prestonsburg, to serve an arrest warrant, and Storz opened fire with a rifle, police said.

Just before 7 p.m. Kentucky State Police were called to assist, Gayheart said. More officers from the Prestonsburg department, and agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives' London and Ashland Offices also went to the scene.

The standoff lasted about three hours, with Storz surrendering about 10 p.m.

Bullet holes could be seen in the home's screens and in the front door on Saturday. At least two police vehicles were lined with bullet holes.

Who were the 3 police officers killed?

The deaths of Floyd County Sheriff's Deputy William Petry, a former state trooper, and Prestonsburg Police Capt. Ralph Frasure, a 39-year law enforcement veteran, were announced early Friday.

Jacob Chaffins, a K9 officer and patrolman for Prestonsburg Police, died Friday evening after succumbing to his injuries.

Were other officers injured in the standoff?

Deputy Darren Lawson of the Floyd County Sheriff's Office, was shot in the leg and remained at University of Kentucky Hospital on Tuesday afternoon in stable condition, Floyd County Judge-Executive Robbie Williams said.

Joe Reynolds, the county's emergency management director, has been released from the hospital. Williams said that he will need surgeries in his eyes.

Gary Wolf, the constable for District 1, was hit in his eyes when the gunman shot through some glass, Williams said. His lens had to be removed from his right eye, rendering him blind in it, Williams said. Wolf has been released from the hospital, and there are hopes that he can get a donor eye, the judge-executive said.

What do we know about Lance Storz?

The Courier Journal could not find any other criminal history for Storz in Kentucky.

After Thursday's incident, Storz was initially charged with two counts of murdering a police officer, five counts of attempted murder of a police officer, one count of attempted murder and one count of first-degree assault of a service animal, court records show.

One of the attempted murder charges is likely to be upgraded given Chaffin's death.

Storz went before Judge Eric. D. Hall virtually on Friday, with contusions covering his face. He was ordered to remain in custody on a $10 million bond. His next court date is July 11. The case will be transferred to Floyd Circuit Court and could become a capital case.

Why were police serving a warrant on Storz?

An emergency domestic violence protective order was issued against Storz on Thursday, court records show.

Floyd County Sheriff John Hunt said that Prestonsburg Police conducted a welfare check at Storz's home before the shooting after a family member reported possible domestic abuse.

Hunt said when officers responded to the home, a woman told officers she had been held against her will for several days and sexually assaulted. The woman was later taken to a hospital.

When are the funerals for the 3 police officers?

All three funerals were scheduled for the Mountain Arts Center in Prestonsburg. Petry's service was held Tuesday. Frasure's is planned at 1 p.m. Wednesday and Chaffin's at 1 p.m. Thursday, Williams said.

Williams also said that the sheriff's department is planning to hold a vigil for Drago on Friday afternoon.

How can I help the police officers families?

The Floyd County Community Foundation created the Floyd County Crisis Fund "to help the officers, their families and the departments involved," said John Rosenberg, vice chair of the fund.
