A few hours after the shooting, friends and relatives of the victims congregated near St. Mark Baptist Church on Spaulding St., to grieve and pay their respects to their lost loved ones.

Dalton previously served eleven years in prison for murdering his then 22-year-old wife, Shannon Dalton, by shooting her in the head in 1998.

The couple - who have three children together, aged six, five and three at the time of their mother's death - had been married for five years.

The children allegedly heard the shooting but did not see anything. Her body was discovered on the floor of their shared living room.

After the shooting, Dalton escaped in his wife’s car but was pulled over a few days later in Tennessee for a traffic violation.

He was taken back to Omaha to face charges. After his eleven years in prison Dalton was released in 2010. Apparently a plea bargain saved him from serving a potential life sentence.

Police have said Dalton will either be driving a red 2007 Chevy Tahoe or a black 2015 GMC Terrain with the license plate VRD559.

They have warned people that he is considered 'armed and dangerous.'

Police have urged people to call 402-444-5656 if they see him or have any information on the homicides.
