AUSTIN (CBSDFW.COM/AP) — One person is dead and three others injured after multiple stabbings — all believed to be done by one person — Friday morning in downtown Austin. Police have a suspect in custody.

The assaults stated at a coffee shop, moved to a nearby Tex-Mex restaurant and ended with the suspect leaping off a roof.

Austin police Sgt. David Daniels said investigators don’t know what provoked the suspect from striking a person inside a coffee shop before fleeing and stabbing two people inside Freebirds World Burrito a few doors down. The man jumped off the roof of the restaurant but survived.

Daniels said he did not know whether the stabbing victims at Freebirds were employees. None of the victims were identified, but Austin-Travis County EMS said one man in his 20s was pronounced dead at the scene. Daniels said a knife was involved in the attack but did not say whether it came from the restaurant. Two other people were treated at the scene along South Congress Avenue, near East Riverside.

Austin police have not released the name of the man arrested but said early on that “no other known suspects are outstanding”. Investigators haven’t said what led to the stabbings.

Police cordoned off a retail plaza near the heart of the popular South Congress shopping corridor, about a mile south of the Texas Capitol Building. Reports of the stabbing came in just after 8 a.m. during the typically congested morning commute.
