D.C. police have charged a 70-year-old man with fatally stabbing a woman during what authorities have described as a domestic dispute Sunday night that left three others injured at a house near the U Street corridor.

Manuel Antonio Ramos, of Northwest, was charged with first-degree murder while armed. Police identified the victim as Santos Ventura, 64, but they did not divulge her connection to the suspect.

Ventura was one of four people stabbed about 9:23 p.m. in the 1400 block of T Street NW. Two additional victims suffered non-life-threatening injuries and one was in serious condition.

The four victims were among at least 10 people stabbed in the District over the weekend, including at least three in an incident on Seventh Street NW in Chinatown early Sunday. Police spokesman Lt. Sean Conboy said a suspect was also in custody in connection with that stabbing incident.

In addition, at least 10 people were shot during the weekend as gunfire was heard in eight widely scattered locations.

The rate of shootings was more than twice the recent rate in the District.

The latest of the shootings was reported at 4:20 p.m. Sunday at 21st Street and Benning Road SE. Earlier Sunday, a shooting was reported about 12:30 a.m. in the 1600 block of R Street SE.

Those attacks came after eight people were shot Saturday.

The latest of Saturday’s attacks was about 9:20 p.m. in the 2800 block of Alabama Avenue SE. The shootings began Saturday morning shortly after midnight, with a wounding in the 3000 block of Eighth Street SE.

A man was shot near Third and Taylor streets NW about 1 a.m., and another about 1:30 a.m. in the 2700 block of Martin Luther King Jr . Avenue SE. Before daybreak Saturday morning, shootings were reported on Chesapeake Street SE and Irvington Street SW. Three men were shot on Irvington.
