At least one firefighter and one civilian were shot when a gunman opened fire on paramedics in East Dallas late Monday morning. Dallas police are still searching for the suspect, who is believed to be in the vicinit. The mayor said the civilian whom the paramedic was trying to help when he was shot is also in intensive care.

Dallas Mayor Mike Rawlings said Monday that An underwent surgery and will "have to undergo extensive medical treatment".

Dallas Police Officers comfort each other on the active shooting scene where a Dallas Fire-Rescue paramedic has been shot.

In addition to the two people found dead inside the home and the paramedic, a fourth person - a Dallas citizen - was also seriously wounded Monday and brought to the hospital, officials said.

The shooting happened in the 3200 block of Reynolds Street in Dallas, just south of I-30 near Dolphin Road.

WFAA-TV reported that according to sources, a bullet broke An's leg and he lost a lot of blood.

"We believe ... as a result of those actions that paramedic's life was saved", Pughes said.

Brown fired at responding police officers at they tried to take cover, including one officer who sustained an injury to his calf, possibly from gunfire, the assistant chief said.

The bystander who was injured is in stable condition, according to Dallas police.

UPDATE 1:05 p.m.: NBCDFW reports the area where the shooting took place is consistently listed as one of the most unsafe areas in Dallas.

Blankenbaker says Brown was acting erratically and killed his roommate before shooting and critically injuring a neighbor outside.

The paramedic, 36-year-old William An, was in stable but critical condition at Baylor University Medical Center in Dallas, said Jason Evans, a spokesman for Dallas Fire-Rescue.

No information was released about the second person found dead in the home, including whether the person knew the gunman or if either of them lived in the house.

Police believe the shooting started as a dispute between the suspect and the gunshot victim.

The shooting took place near the Dallas Fire-Rescue training facility.

Several officers have reportedly been pinned down by gunfire.

Authorities say a Dallas paramedic has been shot while responding to a shooting and that the scene remains active and risky.

At the news conference Monday afternoon, Pughes said officers received a tip the suspected gunman was hiding in a nearby house.
