As of early Monday morning, authorities have not yet released the identities of the gunmen who opened fire on a security officer on Sunday outside a Muhammed cartoon contest near Dallas.
Police were investigating the gunmen’s vehicle for explosives on Sunday night and had not yet removed the bodies of the two gunmen from the street in Garland, Texas.
Garland police spokesman Joe Harn said that the vehicle examination could take a while, according to the Dallas Morning News.
“It’s a very slow, tedious operation that’s going on,” Harn said. “They may be even having to X-ray different things.”
The two gunmen were killed when they drove up to the Curtis Culwell Center in Garland and began shooting at a security guard.
Authorities do not yet know whether the shooting was related to the event inside the Curtis Culwell Center, a contest for the best depiction of Muhammed held by Pamela Geller’s American Freedom Defense Initiative.
