Maryland Suspect in Custody After 3 Deadly Shootings

A suspected gunman is in custody after two people were killed in separate shootings at a mall and grocery store in Montgomery County, Maryland, today, and police say the shootings may be linked to a deadly domestic shooting in the area yesterday.

The suspect, Eulalio Tordil, 62, was taken into custody today in the Aspen Hill, Maryland, area, police said. No one was injured during the arrest.

Montgomery County police said they have reason to believe today's two deadly shootings -- at the Westfield Montgomery Mall and a Giant grocery store nearby -- were related to a fatal shooting at a high school in the area yesterday, adding "that will obviously [need to be] further vetted."

The suspect was apprehended after he was seen eating at a Boston Market, police said.

Three people were shot at the Westfield Montgomery Mall in Bethesda earlier today. One of the victims has died; another is in critical condition and the third suffered non-life-threatening injuries, police said.

A woman was also killed today in a shooting at a Giant grocery store in the Aspen Hill area, about 8 miles away from the mall.

The Prince George's County Police Department said earlier today it was "looking into the possibility" that Tordil, accused of shooting and killing his estranged wife Thursday in the parking lot of High Point High School in Beltsville in Prince George's County, was also the shooter in Montgomery County this morning. Montgomery County police also said earlier they were "investigating a possible link" between Tordil and the two shootings today.

Prince George's County police said Tordil, a Federal Protective Service employee, followed his estranged wife, Gladys Tordil, to the high school Thursday afternoon when she went to pick up her children. Police said Tordil fatally shot his estranged wife and shot and injured a good Samaritan who came to her aid.

Tordil's wife has alleged that Tordil subjected their family to abuse, according to a protective order issued by a Maryland judge against Tordil.

The order was issued on March 17, 2016, and was to remain in place for one year. The judge specifically ordered Tordil to stay away from High Point High School, where Gladys Tordil was murdered.

According to the document, Gladys Tordil alleged that Tordil exposed minor children to "pornographic materials," touched at least one of them inappropriately and subjected them to "intense-military-like discipline - pushups, detention in dark closet."

Gladys Tordil said in 2010 that her husband "slapped me so hard during our altercation, my glasses broke on my face," the document states.

On Tordil's wanted poster from Thursday, authorities noted, "The suspect has made threats to commit suicide by cop."

FPS said Tordil was placed on administrative duties in March after a protective order was issued against him. His duty weapon, badge and credentials were removed. He was subsequently placed on administrative leave, FPS said.
