OKLAHOMA CITY - The woman, who was fatally shot in her home Friday morning, has been identified and police arrested four men in connection to the deadly home invasion.

Oklahoma City police identified the woman as 31-year-old Lisa Batt. Police have not released the name of Batt's boyfriend, who was injured in the incident.

The suspects, Andrew Sandiago, Kevin Osborne Jr,, Steven Bobo and Redmond Brown are all charged with first-degree murder, shooting with intent to kill and robbery with a firearm.

At about 1 a.m., officers were called to the home near NW 56 Terrace and Warren Avenue.

Four masked intruders entered the home and started a confrontation. The assailants then fired several shots and fled, police said.

"It has not been determined whether they were let in or whether they actually forced their way into the house," said Sgt. Paco Balderrama.

Batts died at the scene and her boyfriend was taken to a local hospital, police said.

The injured man called 911 after the intruders fled the scene, police said. His condition has not been released.

Officers said they have not determined a motive.

"In your typical home invasion the suspects go inside, usually tie you up and then clean you out - as far as robbing you and taking your belongings," Sgt. Balderrama said. "That didn't happen in this case."

Police are investigating whether the gunmen and the victims knew one another.

This was the 38th homicide for Oklahoma City in 2008.
