Dr Richard Warn ... Frum Doctor's Homicide Results in 2 Other Deaths

The police investigation into the slaying of a Beachwood doctor took an unusual turn late Friday and early Saturday with a SWAT standoff that ended with two others dead.

Cleveland.com has been following the story since Thursday when the body of Dr. Richard Warn was discovered at his Beachwood home. 

In the ensuing days, police served a search warrant at a South Euclid home connected to Wren that resulted in a tense standoff with a SWAT team.

Two are now dead, and the 10-hour standoff ended with many questions still unanswered. 

Here is what we know so far. 

Dr. Warn's wife, Jane, called 911 saying that she and her family just returned from vacation and did not have a key to the house. 

Her voice shakes as she explains to dispatch that her husband was not answering repeated knocks on the door, even though his car was in the driveway.

Beachwood police arrived a few minutes later to the Brentwood Road home and discovered Dr. Warn dead inside. 

Police suspected foul play in Warn's death, and told reporters that there were no signs of any forced entry into the home. 

Within hours, the Cuyahoga County Medical Examiner's Office released a statement saying Warn died of multiple gunshot wounds. 

Richard was a podiatrist in the Cleveland area for 35 years, according to his obituarypublished in The Plain Dealer. 

Neighbors and coworkers described him as a nice man and a devoted father to a daughter, Danielle, and two sons, Mark and Michael. He remarried over a decade ago and shared his home with his wife, Jane, and three Golden Retrievers. 

"I was in utter shock," said Shelly Zemelman, 59, who lived next door to Warn for 20 years and has known him since childhood. "I ran home. Just utter shock. We were the same age. I just don't know what else to say."

Beachwood police investigators went with a search warrant to a home on the 4300 block of Elmwood Road in South Euclid,  a property Warn owned, county records show.

"We had the EDGE SWAT team assist by clearing the home prior to the detectives conducting the search," Beachwood Chief of Police Gary Haba said.

As the SWAT team approached the home about 7:30 p.m., someone inside the home opened fire. Over the next 10 hours, officers set up camp outside  the home. 

Someone inside the home shot at officers, damaging the windshield of an armored SWAT vehicle, pictured above.

The officers turned fire and retreated, South Euclid police Chief Kevin Niehart said. Negotiators made several unsuccessful attempts to contact the people inside the home. 

None of the officers were hurt during what would become a 10-hour standoff that ended when the SWAT team approached the building. 

Police took gradually more aggressive tactics to get the suspects to surrender before determining that they were deceased. 

In the early hours of Saturday, neighbors saw officers using some sort of battering ram to enter the home, where they discovered two dead men. 

Nietart confirmed that the two men were persons of interest in Dr. Warn's murder.

Police have not release their identities, nor have they said how the two men died.

The Cuyahoga County Medical Examiner's Office did not release their identities as of 7 p.m. Saturday.
