Two women were killed and a toddler was injured in a shooting at Texas A&M University-Commerce dorm on Monday, Feb. 3.

The A&M-Commerce University Police Department identified two women who died in the shooting were sisters.

One of the women, 19-year-old Deja Matts, from Garland, Texas, was a freshman at the school. She was pursuing a degree in public health, officials said Tuesday, Feb. 4.

The other woman was her sister, 20-year-old Abbaney Matts. She was not enrolled at A&M-Commerce, officials said.

Matts’s 2-year-old son was the toddler injured in the shooting. He was treated and later released to the care of family members, university police officials said.

The shooting was reported at about 10:17 a.m. local time on Monday at Pride Rock Residence Hall, which houses freshmen.

A shelter-in-place was lifted after being in place for about two hours, but the residence hall remained blocked off, officials said.

Classes and all campus events have been canceled through Wednesday, and counselors will be available at the student center for anyone who would like assistance, according to WFAA.

School officials said Tuesday that the “shooting appears to be a targeted, isolated event,” ABC News reported. The officials didn’t provide many details.

The suspect, identified as Jacques Dshawn Smith, 21, was arrested and charged with capital murder after surveillance and witness tips led police to him, according to the university’s police department.

Smith is not a student at A&M-Commerce. He is believed to be an ex-boyfriend of Abbaney Matts, according to police.

University officials said the investigation remains active.

“Our hearts go out to everyone in the community who has been impacted by this tragedy,” University President Mark Rudin said Monday.

Texas A&M’s campus in Commerce, Texas, is more than 200 miles north of Texas A&M’s main campus in College Station.
